Question

A triangle with side lengths of 3, 4, and 5 forms a right triangle.

True
False

Answer 1

You can check using the Pythagorean theorem.

\(a^2 + b^2 = c^2\)

If a triangle has sides of lengths a, b, and c, and the sides make the equation above true, then the triangle is a right triangle.

Use a = 3, b = 4, and c = 5, and try them in the equation above.
