Find The Measure Of Each Exterior Angle Of A Triangle. The exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles. So for an equilateral triangle each exterior angle measures.
The sum of exterior angles of any polygon is 360. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles of the triangle. Kaypeeoh72z and 6 more users found this answer helpful.
The first rule states that the Exterior Angle of a Triangle is equal to the sum of the two non adjacent angles.
That angle if the exterior angle. The measure of an exterior angle equals. We know that the three interior angles of any triangle always add up to 180 degrees. It states that the square of the hypotenuse the side opposite the right angle is equal to the sum of the squares of the other two sides.
