Question

A triangle has sides with lengths of 13 meters, 18 meters, and 8 meters. Is it a right triangle?

Answer 1

The Pythagorean Theorem describes the relationship among the three sides of a right triangle

`a^(2) +b^(2) = c^(2) \\8^2+13^2=c^2=208 \\√(208)=14.4\\ 14.4 \\eq 18`--> not a right triangle
