How do you find the measure of angle?

Answer 1

The sum of the angles of a triangle equal 180 degrees. The sum of the angles of a quadrilateral equal 360 degrees.

To find the measure of an angle for a triangle, you must first be given the other two angle numbers, unless it is an equilateral triangle, in which all angles would equal 60 degrees.

To find the measure of a quadrilateral, you must first be given the other three angle numbers, unless it is a square, in which all angles would equal 90 degrees.

Answer 2

you need a protracter line up the start of angle with the line and read the angle!!

Answer 3

Use a protractor.
