This one activity requires young geometers to pull together information they are currently learning with things they have learned previously. Here they rely on understanding something about parallel lines, alternative interior angles,...

This is a mid-module assessment for the 16th lesson in 29 geometry lessons. Individuals demonstrate their understanding of concepts such as vertical and adjacent angles, constructing geometric figures, and triangle congruence criteria.

Students are challenged to identify and measure angles created by parallel lines and a transversal as well as complementary and supplementary pairs.

Practice identifying supplementary, complementary, and vertical angles.

Practice problems finding missing angles.

Practice finding complementary and supplementary angles.

Practice finding angle measures between intersecting lines.

Practice creating equations to solve for missing angles.

In this exercise, students practice identifying complementary and supplementary angles. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.
