Triangles
Triangles – Example 1: The sum of the inner angles of a triangle is \(180°\). So, \(120°\)\(+\)\(35^°\)\(=\)\(155^°\)\(→\)\(180^°\)\(-\) \(155^°\) \(=\) \(25^°\). The unknown angle is \(25^°\) Exercises for Triangles Find the measure of the unknown angle in each triangle. 1) 2) \(\color{blue}{70^°}\) \(\color{blue}{30^°}\) The Best Math Books for Elementary Students
