Answer:

D

Step-by-step explanation:

Using Pythagoras' identity for right triangles

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Here PR is the hypotenuse, thus

13² = 169

5² + 12² = 25 + 144 = 169

Thus Δ PQR is a right triangle because 5² + 12² = 13² → D
