Question

A triangle has side lengths 7 in, 11in, and 9in. Will it form a right triangle? If not, what type of triangle does it form?

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).

Expert Solution

Step 1

In the question it is asked to check whether the given sides (7 in, 11 in, 9 in) form right angle or not. If they don't form it is asked to check triangle's nature.
