Triangle sum theorem definition geometry
WebMar 26, 2016 · Geometry For Dummies. There are four addition theorems: two for segments and two for angles. They are used frequently in proofs. Use the following two addition theorems for proofs involving three segments or three angles: Segment addition (three total segments): If a segment is added to two congruent segments, then the sums are congruent. WebTranscript. The triangle sum theorem states that the sum of the measures of angles in a triangle is 180°. So, if a triangle has two angle measures given, it is possible to find the measure of the third by subtracting the two given measures from 180°. Recall that the sum of a linear pair of angles, which are adjacent angles that lie on the ...
