THE INTERIOR PROBLEM
geometry · interior angles of polygons
To find the measures of the interior angles of polygons [8.G.A.5].
THE INTERIOR PROBLEM is a Grade 8 geometry game for finding missing interior angles in polygons. Game cards provide sets of angle measures, and students use the properties of polygon angle sums to determine the unknown value. Because different cards can involve different polygons, students must first identify the relevant total before solving.
Use it in a small group when students are reviewing interior-angle relationships and algebraic reasoning. Ask students to state the polygon’s interior-angle sum before calculating the missing angle.
