"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
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)
