What does this picture tell you about the validity of SSA for proving two triangles are congruent? |
SAS congruence
SAS congruence[br]Given triangle DEG with two sides and included angle.[br]Move the sliders to adjust the sides AC=ED and BC=EG[br]Also move point B to make angle C= angle E[br]Now place triangle ABC over DEG.
Do the triangle overlap each other completely?[br]If yes then triangles are congruent.[br]So all the corresponding sides and angles of both triangles will be equal.
