5. A right triangle has side length of 40mm, 75mm, and 85mm.

a) Sketch the right triangle and draw squares around each side of the triangle.

b) What are the areas of the three squares?

A=40mm B=75mm C=80mm

A=40

*² B=75*

*²*

*C=80*

*A=40x40 B=75x75 C=80x80*

A=1600mm B=5625 C=7225

A=1600mm B=5625 C=7225

c) Write an addition statement using the areas of these three squares.

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

1600+5625=7225

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

*200mm. Is the triangle a right triangle? Explaing your reasoning.*

a+b=c

120+160= 280

280≠200

It is not the a right triangle because the leg of the triangle did not equal the hypotenuse.
