Andrea is given AABC and told that a? + b2 = c? She draws right triangle RTS with legs
measuring a and b and hypotenuse measuring x. Which best describes what Andrea should
do in order to prove that AABC is a right triangle?
b
b
Show that a² + b2 = c2, so ZAZR. This means AABC ARTS, and so ZC is a right angle and
so AABC is a right triangle.
Show that c = x, so AABC = ARTS and so ZC ZS. This means ZC is a right angle, and so
AABC is a right triangle.
Show that c = r, so AABC ~ ARTS and so ZC ~ ZS. This means ZC is a right angle, and so
AABC is a right triangle.
Show that c + x, SO AABC ARTS and so ZC ZS. This means ZC is a right angle, and so
AABC is a right triangle.
