WebThe sum of the angles of a triangle is 180 degrees. The measure of an exterior angle of a triangle is equal to the sum of the remote interior angles. The measure of an exterior angle of a triangle is greater than that of either remote interior angle. When two angles of a triangle are equal, their opposite sides are equal, and vice versa. WebThe Corresponding Angles Postulate states that, when two parallel lines are cut by a transversal , the resulting corresponding angles are congruent . So, in the figure below, if , then . The converse is also true; that is, if … WebJul 20, 2024 · By definition: when the measures of two angles sum up to 180°, we call the pair “supplementary.” In fact: if any two angles form a linear pair (see the image below), then they are supplementary. This concept is called the linear pair postulate , and it is a key piece in understanding the Consecutive Interior Angles Theorem … log into myscholarshop
