Question

state which of the following is true ​

Answer 1

you can do it by the Pythagoras theorem

Answer 2

Answer:

The Pythagoras theorem states that the sum of squares of base and perpendicular in a right angled triangle equals to the square of its Hypotenuse.

In this given figure, Perpendicular = AB

Base = CA

Hypotenuse = BC

P² + B² = H²

Hence, that statement AB² + CA² = BC² is true.
