Question

help! I am stumped on this geometry problem:
You plan to sew two triangles of fabric together to make a square for a quilting project. The triangles are both right triangles and have the same side and angle measures. What must also be true about the triangles in order to guarantee that the opposite sides of the fabric square are parallel? I think the answer is: the two angles that are not the right angles have to be the same - 45 degree angles.

Answer 1

right

Answer 2

the 2 legs of each right angled triangle must be equal to make the square
this only occurs when 2 angles are both = 45 degrees

Answer 3

thank you!

Answer 4
