Pythagoras + Textbook Questions

Adrian's Pythagorean Relationship Post

1. Answer in a short paragraph and with diagrams
The two legs Leg A and Leg B are equal to c which is called the hypotenuse.

2.Solve the missing side length
a+b=c
a=(12x12)+(5x5)
a=(144)(25)
a=144+25=169cm
missing side length=169cm2

3.Is it a right triangle?

a+b=c

(8x8)+(6x6=(11x11)

64+36=121

It is not a right triangle because the legs arent equal to the hypotenuse.
