What Grade 7 geometry covers
Grade 7 geometry includes angle facts that come from intersecting lines and nearby angle pairs. Students use adjacent angles, vertical angles, congruent angles, and straight-line facts to write equations and find unknown measures.
Angles become connected facts
At this level, angles are not only named by size. Students also learn how one angle measure can tell them another angle measure in the same diagram, especially when angles are marked congruent.
Explain the angle relationship first
Start with the definition, study the marked diagram, then try the playground or practice section. The goal is to explain the angle relationship before calculating.
