Congruent triangles are triangles having corresponding sides and angles to be equal. Note that in congruent triangles corresponding parts are equal and we write in short cpct for corresponding parts of congruent triangles. Depending on similarities in the measurement of sides, triangles are classified as equilateral, isosceles and scalene.
