Question

Second sum . Using Pythagoras theorum . Don't spam. Answer me fast as possible . I will mark you as brainliest

Answer 1

Yes it is right angles as it satisfies Pythagoras Theorem

z² =y²-x²

Rearranging it,

z² + x²=y²

E F is hypotenuse.

EDF is right angle as D is not part of hypotenuse it must be in opposite side, therefore, EDF is right angle

Answer 2

In Triangle DE = x EF = y and DF = Z

It is given that z² = y² - x²

For right angle triangle the necessary equation is this i.e. y² = z ² + x²

So it is a right angle triangle.
