Question

plz give me the answer of this question .........​

Answer 1

given=pR=RQ

to prove =PQ^=2PR^

Proof=PQ^=PR^+RQ^【BY PYTHAGORAS THEOREM】

PQ^=PR^+PR^:. (PR=RQ)

SO,

PQ^=PR^+PR^

PQ^=2PR^

HENCE PROOVED

Answer 2

Answer:

Step-by-step explanation:

Let the two equal sides of the isosceles triangle be X

Now applying Pythagoras property in triangle PQR,we get

PQ²= PR² +RQ²

=X² + X²

=2X²

= 2(PR)²

Hence ,proved.

(Sorry that I couldn't upload the figure for this question .but you can draw it by yourself .just draw a right angled triangle ,right angled at R)

I hope this would help you.
