Pythagorean Relationship

1.

a2 + b2 + c2.

Means leg (a2) + leg (b2) = the hypotenuse

2.

12 cm side is A and the 5 cm is B.

We need to find C.

C2=A2+B2

C2=12cm2+5cm2

C2=144cm2+25cm2

C2=169cm2

Now you have to find the square root.

Answer - 13 cm2

3.

To find if it is right triangle it must apply a2+b2=c2.

8cm - a

6cm - b

11cm - c

c2=a2+b2

c2=8cm2+6cm2

c2=642+362

c2=100cm2

Square root 100.

= 10

No it is not a right triangle.
