Final answer:
When you cut a square into two identical triangles, you create two right triangles.
Step-by-step explanation:
When you cut a square into two identical triangles, you create two right triangles. A right triangle is a triangle that has one angle measuring 90 degrees, also known as a right angle. In this case, when you cut the square in half diagonally, each triangle will have one right angle. The other two angles will add up to 90 degrees, making them complementary angles.
