Andrea is given AABC and told that a² + b2 = c. She draws right triangle RTS with legs
measuring a and b and hypotenuse measuring 2. Which best describes what Andrea should
do in order to prove that AABC is a right triangle?
-Show that c = 2, so AABC ~ ARTS and so ZC ~ ZS. This means ZC is a right angle, and so
ABC is a right triangle.
ARTS and so ZC
ZS. This means ZC is a right angle, and so
-Show that c + x, so AABC
AABC is a right triangle.
-Show that c = 2, SO AABC & ARTS and so ZCE ZS. This means ZC is a right angle, and so
AABC is a right triangle.
-Show that a2 + b2 = c2, so ZA
so AABC is a right triangle.
ZR. This means AABC
ARTS, and so ZC is a right angle and
