State the four conditions of congruency of two triangles.
Triangles
Original Khojo Papers practice question — not from a past board paper.
Two triangles are congruent by the SAS criterion if two sides of one triangle are equal to two sides of the other and the angle included between those two sides is also equal.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
The equal angle must be the one contained between the two pairs of equal sides.

State the four conditions of congruency of two triangles.
Triangles
Two triangles are congruent by the RHS rule when:
Triangles
In triangle ABC, AB = AC and D is the midpoint of BC. Prove that AD is perpendicular to BC.
Triangles
Prove that the angles opposite to the equal sides of an isosceles triangle are equal.
Triangles
In triangles ABC and PQR, AB = PQ, BC = QR and angle B = angle Q. State the criterion by which the triangles are congruent and name three pairs of equal parts that follow.
Triangles
Explain why SSA is not a valid criterion for the congruency of two triangles.
