My question is:

Question 10 pg.92

10. A triangle has side of 120 mm, 160 mm, and 200 mm.

Is the triangle a right triangle? Explain your reasoning?

Answer:

Yes the triangle is a right triangle. The sum of the areas of the two smaller

squares are equal to the area of the largest square.

2 2 2

120 + 160 = 200
