Answer: The measure of ∠PRQ is equal to 90 degrees.


Step-by-step explanation:

Given: In triangle PQR,

[tex]r^2=p^2+q^2[/tex]

By converse of Pythagoras theorem,

Δ PQR must be a right triangle.

And in right  triangle, the angle opposite to the longest side is right angle.

Therefore, ∠PRQ=90°

∴ The measure of ∠PRQ is equal to 90 degrees.

  • The converse of Pythagoras theorem says that if the square of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.
