Question

How do you find measurements of quadrilaterals

Answer 1

1. Add together the measurements that you know
2. Subtract the sum of those from 360 to determine what the measurement of that angle is

Answer 2

You can find the measurements of the angles of any shape with the equation 180(s-2), where s is the sides. For example, s would be 3 for a triangle, 4 for a quadrilateral, 5 for a pentagon, etc.

A quadrilateral has 4 sides

180(4-2)

180(2)

The sum of all of a quadrilateral's sides would add up to 360.
