Congruent Triangles Snap!
In this activity there are 14 triangles. Students must match them into pairs that are definitely congruent.
Once they have matched them congruent triangles, they must then work out the missing sides and angles.
As an extension students could cut out the cards and make a poster of them, explaining for each pair how they know they are congruent. They could also make their own pair of congruent triangles.
As a further extension, pupils could also use the sine and cosine laws to work out the missing sides and angles in the triangles. Answers for this are included.
