9-124.

On a coordinate grid, draw a triangle with vertices at (2,6), (2,2), and (5,6). 9-124 HW eTool (Desmos). Homework Help ✎

Find the lengths of each side of the triangle. What is the perimeter?

What type of triangle is formed by these points?

**Justify**your answer.

To find the hypotenuse, we can use the Pythagorean theorem: *a*^{2} + *b*^{2} = *c*^{2}

If the legs are 3 and 4, how long is the hypotenuse?

After finding the hypotenuse, find the perimeter.

The triangle has a right angle so it is a right triangle.
