Web13 jan. 2024 · Since a triangle is essentially half of a quadrilateral, its angle measures should be half as well. Half of 360 ° is 180 °. For example, the sum of the angles of the quadrilateral below is 360 ° because it consists of four 90 ° angles. The pink triangle is half of this, therefore the sum of its angle measures should also be half ( 180 °).
