These cards encourage students to explore which triangles they can copy to produce congruent triangles. If they cannot they are then asked what information they require. 8.G.A.5 , 7.G.A.1

Standards

Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.
Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.

Exactly what I needed. Students investigated and came up with congruence rules on their own :)

Thanks, really great for getting kids to work out the rules for themselves.
