Andrea is given AABC and told that a? +62 = c.She draws right triangle RTS with legs
measuring a and b and hypotenuse measuring z. Which best describes what Andrea should
do in order to prove that AABC is a right triangle?
Show that c+I. SO AABC ARTS and so ZC & S. This means ZC is a right angle, and so
AABC is a right triangle.
Show that a + b = e. so ZA= R. This means AABC = ARTS, and so ZC is a right angle
and so AABC is a right triangle.
Show that c = 2, SO AABC = ARTS and so ZC & ZS. This means ZC is a right angle, and 2
AABC is a right triangle.
Show that c = I. SO AABC ~ ARTS and so ZC ~ ZS. This means ZC is a right angle, and so
AABC is a right triangle.
