    Mathematics

    What is triangles & pythagoras?

    Triangle geometry covers congruence, similarity, and the Pythagoras theorem relating the sides of a right triangle.

    Why it matters

    Triangles carry the heaviest proof weight in Class 9–10 geometry and feed trigonometry.

    Key concepts you will practise

    • Congruence criteria (SSS, SAS, ASA, RHS)
    • Similarity and the basic proportionality theorem
    • Pythagoras theorem and its converse
    • Areas of similar triangles

    Tips that save marks

    • Mark equal sides and angles on the diagram before writing a proof.
    • The converse of Pythagoras tests whether a triangle is right-angled.

    Frequently asked questions

    What is the difference between congruent and similar triangles?

    Congruent triangles are identical in size and shape; similar triangles have the same shape with proportional sides.

    Does Pythagoras work for all triangles?

    No — only for right-angled triangles.
