Congruent triangles criteria with examples showing two triangles with same side lengths and angle sizes.
Diagram showing the criteria for identifying congruent triangles: SSS, SAS, ASA, and RHS with corresponding labelled triangles.
Identifying congruent triangles using SSS (side, side, side) criteria with two triangles both having sides of 3 cm, 5 cm, and 6 cm.
Identifying congruent triangles using SAS (Side, Angle, Side) rule with two triangles having sides of 3 cm, 5 cm, and an included angle of 70 degrees.
Identifying congruent triangles using ASA (Angle, Side, Angle) with two example triangles showing two angles and the included side as the same.
Identifying congruent triangles using RHS criteria with examples of right-angle triangles having the same hypotenuse and one identical side.
Illustrating that two triangles are not necessarily congruent if they share two equal sides and a non-included angle.
