## How do you find the missing side of a rectangle?

Explanation: To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter.

You now have the total length for the remaining 2 sides.

This number divided by 2 is the width..

## What do the side of a triangle add up to?

The most basic fact about triangles is that all the angles add up to a total of 180 degrees. The angle between the sides can be anything from greater than 0 to less than 180 degrees. The angles can’t be 0 or 180 degrees, because the triangles would become straight lines. … So, 45º means 45 degrees.

## How do I find the third side of a triangle?

The Triangle Inequality theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.So, difference of two sides
