Question

∆PQR is an isosceles triangle in which angle R=90°. If PR=6cm,
then PQ=​

Answer 1

Answer:

$6 \sqrt{2}$

Step-by-step explanation:

triangle PQR is isosceles triangle

hence , if one angle is 90

then other two angles are congruent

ie. 45 degree

Now in triangle PQR,

PR = PQ. ( isoceles triangle theorem)

hence,

${pr}^{2} + {qr}^{2} = {pq}^{2}$

${6}^{2} + {6}^{2} = {pq}^{2}$

$pq = 6 \sqrt{2}$

6√2
