Question

tell whether the triangle is a right triangle. Explain.

A. PQR is not a right triangle because $5^{2}$+$12^{2} \neq 13^{2}$.

B. PQR is not a right triangle because $5^{2} + 13^{2} \neq 12^{2}$.

C. PQR is a right triangle because $5^{2} + 13^{2} = 12^{2}$ .

D. PQR is a right triangle because $5^{2} + 12^{2} = 13^{2}$.

Answer 1

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
