perpendicular to AC. Then which of the following options will hold true?
A. AD=DCXAC
B. AB square=ADXAC
C. AB square=ADxDC
D. AB square=DC square+AD square​

Answer 1

Answer:

(D)is the correct answer.

Explanation:

Take a hypotenuse as under root 2.

perpendicular as 1 and base also as 1.

according to 4 option.

(AB) square means 1 square.

is equal to 1.

AD=DC

AC=under root 2.

half of under root 2 is under root 2 upon 2.

under root 2 upon 2 square is 2 upon 4

means 1 upon 2

1 upon 2 means half

and half + half is equal to 1.

So,Option (D) is the correct answer.
