PART 1: Exploring AAA

Move point A' or B' to try and create different triangles with the three given angle measures.

PART 2: Exploring SSS, SAS, AAS, ASA

Move the red dots around to try and create different triangles. A green triangle represents congruent triangles and orange triangle represents non-congruent triangles.

PART 3: Exploring SSA

Move the green dot around to try and create different triangles.

PART 4: Exploring HL

Move the blue dots around to try and create different triangles. A green triangle represents congruent triangles and orange triangle represents non-congruent triangles.
