Question

In angle PQR, if PR square + QR square, state with reason whether angle PQR is right angled triangle or not

PLZ ANSWER ME
​

Answer 1

yes it is right angle triangle

Answer 2

Step-by-step explanation:

This is converse of Pythagoras theorem

We can prove this contradiction sum q ²=p ²+r ²

in ΔPQR while triangle is not a rightangle

Now consider another triangle ΔABC we construct ΔABC AB=qCB=b and C is a Right angle

By the Pythagorean theorem (AC) ²

=p ²+r ²

But we know p ²+r ²=q ²

and q=PR

So (AB) ²=p ²+r ²=(SR) ²

Since PQ and AB are length of sides we can take positive square roots

AC=PQ

All the these sides ΔABC are congruent to ΔPQR

So they are congruent by sss theorem

Hope i am right

Here the explaination
