Angle Dominoes
geometry · complementary, supplementary, and congruent angles
To identify and find measures of complementary, supplementary and congruent angles [7.G.B.5].
Angle Dominoes is a Grade 7 geometry game for identifying complementary, supplementary, and congruent angles. Each domino shows angle measures, and players can connect pieces when the adjacent angles add to 90°, add to 180°, or have equal measure. Choosing a legal match requires students to classify the relationship rather than simply calculate an isolated missing angle.
Use it with partners or a small group when angle vocabulary needs repeated application in a familiar domino format. Ask students to name the relationship each time they place a tile and explain the calculation that proves it.
