#1  right triangles

#2  isosceles triangles

#3  Quarter square triangles are smaller within a block, usually having the longest side against a square or the base of a half square triangle and have no right angle (90 degrees) but half square triangles are usually bigger taking up more of the design of the block.  Quarter square triangles are also usually pieced with other quarter square triangles forming a half square triangle.

#4  7/8 of an inch  (0.875 inch)

#5  1 and 1/4 inches (1.25 inches)

1) Right. 2) Isosceles 3) Length and/or grain. I quickly gauge myself by color variation also. 4) 0.875"-7/8 inch. 5) 1.25"- 1 1/4 inch. Fun!

Question 3 - by determining whether the grain line runs along the short or long side of the triangle

Question 4 - 7/8 "

Question 5 - 1-1/4"

Wow - I had to think all the way back to Jr. High geometry class for this one!  Loved it - thanks for the brain buster!!!!!

Questions 1 and 2 are both Right isosceles triangles

Question 3 - I would say if a square block has four equal triangles, they are quarter triangles.

Question 4 - Add 7/8"

Question 5 - Add 1.25 (1-1/4")

I'm going to take some time to look more closely at the quilting tools and read through the website. Very interesting. I do have trouble cutting those weird sizes. Oh heck, I admit, I have trouble cutting any size accurately!

This is a fabulous product. I learned so much just from checking out the web page. If I don't win, I'm buying some anyway!!

Anwers to quiz:

1. Right Triangle

Question #1 - is right isosceles triangles

Question #2 - right isosceles triangles

3. The quarter-square triangles are smaller and usually (but not always) form an X shape within a particular square (when they do form the x, they're composed of 4 pieces of fabric all being triangles formed to make a square). Any square within the block that only has two pieces and forms a diagonal line is half-square. If it looks half square, but one of the halves has two equally-sized pieces on it (so there are 3 pieces of fabric total in the square), then it's actually quarter-square.

Q1 answers 1-3 are all correct. Half square triangles are right isosceles because they have one 90

angle and two 45 degree angles.

Q2 again answers 1-3 are correct. Quarter square triangles are right isosceles. See explanation above.

Q 3 size and appearance alone doesn't differentiate, but grain line and bias edges will.

Q4 add 7/8 inches to finished size measurement for half square triangles.

Q5 add 1.25 inches to finished size measurement for quarter square triangles.

Question #1: Right Isosceles Triangle

Question #2: Right Isosceles Triangle

Question #3: Focus on each patch. Each patch is usually made of one of 4 combinations of squares, half triangles and quarter triangles. The half triangles will have the gain line on their short sides and the half triangles will have the gain line on their long side.

Question #4: Add 7/8 or (.875)"

Question #5: Add 1.25 or (1.25)"

Question #1 Right isosceles triangles

Question #2 Right isosceles triangles

Question #3 1. Look at the grain. The 1/2 square have the long side on the bias. The 1/4 square has the 2 short sides on the grain. Also look at the patch. One square=one square in the patch. 2 squares made up of 2 triangles=1/2 square triangle. 3 squares-1 large triangle with a long side which also has 1 small triangle on each small side =1/4 square triangle. 4 triangles in patch =1/4 square triangles.

Question #4 1/2 square triangle needs exactly 0.875 which is not on the standard ruler and therefore the correct answer would be 1/2"

Quesion #5 1/4 square triangle needs exactly 1.25" which are not on a standard ruler therefore the correct answer would be 1 1/4"

Question #1 Right isosceles Triangles

Question #2 Right isosceles Triangles

Question #3 1/2 square triangles have the short sides on the grain, the 1/4 square triangles have the long side on the grain. You can also look at the patch-if are 2 triangles of equal size, you have 1/2 square triangles, if there are 3-flying geese for example-the 2 are 1/2 square triangles, if there are 4 equal size triangles, you have 1/4 square triangles.

Question #4 1/2" for  half square triangles

Question #5 1 1/4" for quarter square triangles (The exact amounts are 7/8" for the 1/2 square and 0.875 for the 1/4 square and since your ruler allows for these exact measurements each triangle will turn out right with no addition alterations. Your product is fabulous!!!!!!!!!!!)

Question #5

Answer 1: Right isosceles triangles

Answer 2: Right isosceles triangles

Answer 3: Grain runs along the short sides of Half Square Triangles with the bias along the long sides.  Grain runs along the long sides of Quarter Square Triangles with the bias along the short sides.

Answer 4: Using a conventional quilt ruler you would add 7/8" (or 0.875" which is as close to 0.854" as you can get) for the seam allowance to make Half Square Triangles.

Answer 5: Using a conventional quilt ruler you would add 1 1/4" (or 1.25" which is as close to 1.207" as you can get) for the seam allowance to make Quarter Square Triangles.

Hello!  Your rulers and tools look amazing especially for folks that have prolems with thier hands!

Answers to the above questions as follows:

1. Right Isoceles

2. Right Isoceles

3. The fabric grain runs along the short sides on a 1/2 square triangle, the fabric grain runs along the  long side of a 1/4 square triangle.

4. Although the seam allowance should be a scant quarter of an inch, the finished size with a ruler for half triangle would be .875 (7/8") on the ends of the triangle.

5. Again, seam allowance is scant quarter of an inch for a quarter square triangle would be 1.25 (1 1/4").

3. straight of the grain may be one way. But the obvious way for me is to look at where the right angle the triangle points.  If it points into the center of the square - it is quarter sq triangles.  If the right angle points to the outside of the sq, then it is a half sq triangle.  Plus each half of the Half sq triangle forms two sides of the square and each Qtr Sq triangle forms one side of the square.

Q3: The grain.  Fabric grain runs up and down, and side to side.  When we cut a square and then cut it in half on the diagonal, we form half square triangles; which the grain can run along the long side or the short side.  If we cut a square in half on the diagonal twice, we create quarter square triangles and the grain can only run along the long sides.  This makes it much easier to tell them apart in a block, along with their size as well.

4.  Half-square triangle you add:  7/8 in. (exact amount 0.854")

5. Quarter-square triangles you add: 1 1/4 in. (exact amount 1.207")

answer 1. isosceles triangle    2. isosceles triangle     3. fabric grain - half square triangle grains runs along short sides (across and up and down) square is cut into 2 pieces. quarter square triangle grain runs  on the long side (diagonally) square is cut into four pieces.

1.  Right isosceles triangle

2.  Right isosceles triangle

3.  Half-square and quarter-square triangles are cut so that the straight of grain is along the outside edges of the finished unit.  For half-square triangles, this means the short sides of the triangle are on the straight of grain.  For quarter-square triangles, the long side is on the straight of grain.  You can tell which is which in a block by looking at how much space a triangle takes up within its square.  As the names suggest, a half-square triangle makes up ½ of the square it is sewn into and a quarter-square triangle makes up ¼ of the square.
