Step 1: In the figure, ΔPQR is a right triangle.
Step 2: From the figure, PQ = 5 in. and QR = 5 in.
Step 3: According to Pythagorean theorem, in a right triangle, square of the hypotenuse = sum of the squares of the other two sides.
Step 4: In ΔPQR, PR is hypotenuse.
Step 5: From ΔPQR, PR2 = PQ2 + QR2
Step 6: PR2 = 52 + 52 = 25 + 25 = 50
Step 7: PR = 50
Step 8: The length of the side PR = 50 in.
