"A²+B²" stands for the two legs."C²" stands for the hypotenuse.If the two legs and the hypotenuse are equal the triangle is right.

Ex.

Side length Area Formula

A 6 36 A²+B²=C²
B 8 64 6²+8²=10²
C 10 100 36+64=100

100=100(right triangle)

A²+B²=C²

12cm+5cm=C²

144+25cm=C²

C²=169cm²

C=13cm

A²+B²=C²

8+6=11

64²+36²=121²

100cm²=121cm²

(This is NOT a Right Triangle because the legs and the hypotenuse are not equal)
