Congruence of Triangles
Congruence of Triangles
Triangles are congruent when all corresponding sides and interior angles are congruent. The triangles will have the same shape and size, but one may be a mirror image of the other.
A polygon made of three line segments forming three angles is known as 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, D ABC and D PQR are congruent triangles. This means,
Vertices: A and P, B and Q, and C and R are same.
Sides: AB=PQ, QR= BC and AC=PR;
Angles: Ð A = Ð P, ÐB = ÐQ and Ð C= Ð R.
