Congruent Triangles
Congruent triangles are triangles that take the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal.
We can tell whether two triangles are coinciding without testing all the sides and all the angles of the two triangles. In this lesson, we will consider the 4 rules to prove triangle congruence. They are called the SSS rule, SAS rule, ASA dominion and AAS rule. In another lesson, we will consider a proof used for right triangles chosen the Hypotenuse Leg rule. As long as one of the rules is true, information technology is sufficient to prove that the two triangles are congruent.
The following diagrams show the Rules for Triangle Congruency: SSS, SAS, ASA, AAS and RHS. Accept notation that SSA is non sufficient for Triangle Congruency. Ringlet down the page for more examples, solutions and proofs.
Side-Side-Side (SSS) Rule
Side-Side-Side is a dominion used to prove whether a given set of triangles are congruent.
The SSS rule states that:
If iii sides of one triangle are equal to three sides of another triangle, and so the triangles are congruent.
In the diagrams below, if AB = RP, BC = PQ and CA = QR, then triangle ABC is congruent to triangle RPQ.
Side-Angle-Side (SAS) Dominion
Side-Angle-Side is a rule used to prove whether a given fix of triangles are congruent.
The SAS rule states that:
If two sides and the included angle of one triangle are equal to two sides and included angle of another triangle, and then the triangles are coinciding.
An included angle is an bending formed by two given sides.
Included Angle Not-included bending
For the 2 triangles below, if AC = PQ, BC = PR and angle C< = angle P, then by the SAS dominion, triangle ABC is congruent to triangle QRP.
Angle-Side-Angle (ASA) Rule
Angle-side-angle is a rule used to testify whether a given set of triangles are congruent.
The ASA rule states that:
If two angles and the included side of ane triangle are equal to two angles and included side of another triangle, then the triangles are congruent.
Angle-Angle-Side (AAS) Rule
Angle-side-angle is a rule used to evidence whether a given set of triangles are congruent.
The AAS rule states that:
If 2 angles and a non-included side of one triangle are equal to 2 angles and a not-included side of another triangle, then the triangles are congruent.
In the diagrams beneath, if AC = QP, bending A = angle Q, and angle B = bending R, then triangle ABC is congruent to triangle QRP.
Three Ways To Prove Triangles Coinciding
A video lesson on SAS, ASA and SSS.
- SSS Postulate: If in that location exists a correspondence between the vertices of two triangles such that iii sides of one triangle are coinciding to the corresponding sides of the other triangle, the ii triangles are congruent.
- SAS Postulate: If there exists a correspondence between the vertices of two triangles such that the two sides and the included angle of one triangle are congruent to the corresponding parts of the other triangle, the two triangles are congruent.
- ASA Postulate: If there exits a correspondence between the vertices of two triangles such that 2 angles and the included side of one triangle are congruent to the respective parts of the other triangle, the two triangles are congruent.
