Model how to find a missing exterior angle with this eighth-grade geometry worksheet!

This eighth-grade geometry worksheet introduces students to the Triangle Angle Sum Theorem and has them practice finding a missing interior angle in a triangle.

Students use the Exterior Angle Theorem to solve for the variable in triangles where two or more angle measures are linear algebraic expressions.

Students use the Triangle Angle-Sum Theorem to solve for the variable in triangles where two or more angle measures are linear algebraic expressions.

How much does your child know about triangles? Can they figure out the missing angle in each of these triangles?

Turn your child into a geometry detective! How many degrees is each missing angle in these quadrilaterals?
