Right triangles have three sides:
Right triangles have three sides:
Two legs (the sides that make the right angle)
Two legs (the sides that make the right angle)
One hypotenuse (the side that doesn't touch the right angle, the longest side)
One hypotenuse (the side that doesn't touch the right angle, the longest side)
We call the legs a and b, and the hypotenuse c. You can switch a and b, but the hypotenuse MUST be c!
