Why Lesson Planet?
In this angle measurement learning exercise, 7th graders use the three triangles and their two given sides to find the degree of measure for the angle 'n.' Students use the diagram with three given sides to help them find the four different angles. Students draw an example triangle using the given angles and sides. Students then write and solve equations to help them find the measurements for the missing angles in the last triangle. Students finish with two test prep questions using angles.
