A closed polygon made of three line segments forming three angles is known as a Triangle.
Two triangles are said to be congruent if their sides have the same length and angles have same measure. Thus, two triangles can be superimposed side to side and angle to angle.

In the above figure, Δ ABC and Δ PQR are congruent triangles. This means,
Vertices: A and P, B and Q, and C and R are the same.
Sides: AB=PQ, QR= BC and AC=PR;
Angles: ∠A = ∠P, ∠B = ∠Q, and ∠C = ∠R.
Congruent triangles are triangles having corresponding sides and angles to be equal. Congruence is denoted by the symbol “≅”. From the above example, we can write ABC ≅ PQR. They have the same area and the same perimeter.
