Question

A POR is an isosceles right angled triangle. Angle PQR = 90°, PQ-4 cm then
length of segment PR is
(A) 4 cm (B) 4√3 cm (C) 4√2 cm

(D) 16 cm​

Answer 1

Answer:

$. = = = = 2305 \times \frac{?}{?}$

Answer 2

Answer:

4√2 cm

Step-by-step explanation:

PQR is isosceles triangle

and

given that PQ =4 cm

in isosceles triangle two sides are equal

and PQR = 90°

By using Pythagoras theorem

( hypotheses)² = (side)²+ (side)²

let PR = x

x² = 4²+4²

= 16+16

= 32

x=√32

x = 4√2
