Finding Missing Interior and Exterior Angles of Triangles #1

Find the measures of missing interior and exterior angles of triangles with this geometry worksheet! In this one-page practice worksheet, students will be given six problems with different triangle diagrams. In each diagram, two interior angles of the triangle are given and students will need to find the value of either the third interior angle or the remote exterior angle. Problems start with whole number angle measures and progress to decimal angle measures (to the tenths place). Designed for eighth-grade learners, this geometry worksheet is a great way to help students hone their understanding of triangle theorems and how to apply them in practice.
