Exterior Angle Theorem For Triangles, Practice Problems - Geometry

This geometry video tutorial provides a basic introduction into the exterior angle theorem for triangles. It explains how to use it solve for x and y. It describes the difference between interior angles and exterior angles as well as the remote interior angles. It contains plenty of examples and practice problems.

[@triple_gem_shining]

😵‍💫

[@triple_gem_shining]

you can also do it the long way, all triangle sum of angles is 180.. then find that 3rd angle is 80.. every straight line is angle 180.. then minues angle 3 from 180.. giving 100degrees for exterior.
