Gidget built a triangular window frame with side lengths that measure 13 inches, 16 inches and 29 inches. Is the window frame that Gidget created a right triangle?

• Yes, the sum of the squares of the smaller sides equals the square of the longest side

• No, the sum of the squares of the two shorter sides does not equal the square of the longest side.

• Yes; the sum of the two shorter sides equals the length of the longest side.

• No, it does not make a triangle.
