Matching Triangles
geometry · finding and comparing areas of triangles
To solve and compare areas of triangles [7.G.B.6].
Matching Triangles is a Grade 7 geometry activity where students first predict which triangles have equal area and then verify the matches by measuring and calculating. One partner pairs triangles based on visual clues such as common base and height, and the second partner measures the dimensions and applies the triangle-area formula. The two-phase format separates geometric reasoning from computation.
Use it for partner work when students are learning that triangles can have the same area even when they do not look identical. Comparing predicted matches with calculated areas creates a natural discussion about base, height, and what actually determines area.
