Congruence means two triangles have exactly the same shape and size. This happens when all corresponding sides and angles are equal.
You can use rules like SSS, SAS, ASA, and RHS to determine if two triangles are congruent.
SSS (Side-Side-Side) states that if all three sides of one triangle match the three sides of another triangle, the triangles are congruent.
Congruent triangles are identical in size and shape, while similar triangles have the same shape but may differ in size.
It helps in proving shapes identical, solving geometric problems, and understanding properties of figures.
RHS (Right angle–Hypotenuse–Side) states that two right-angled triangles are congruent if their hypotenuse and one corresponding side are equal.
Yes. Since their sides and angles are identical, their area is also the same.
No. AAA only shows similarity, not congruence, because size may differ.
