GCSE Maths - Congruent Triangle Rules #103

The video tutorial explains how to determine if two triangles are congruent, meaning they have the same shape and size, though they may differ in orientation. It introduces four rules for proving congruence: SSS (side-side-side), SAS (side-angle-side), AAS (angle-angle-side), and RHS (right angle-hypotenuse-side). Each rule is explained with examples, highlighting the conditions under which triangles can be considered congruent.

What does it mean for two triangles to be congruent?

• They have the same shape and size.

• They have the same perimeter.

• They have the same area.

• They have the same color.

Which rule states that two triangles are congruent if all three sides are of equal length?

• SAS

• SSS

• RHS

• AAS

In the SAS rule, where should the angle be located?

• Outside the triangle

• At the base of the triangle

• At the top of the triangle

• Between the two sides of equal length

What does the AAS rule require for two triangles to be congruent?

• A right angle and two sides

• Two sides and an angle in the same position

• Three sides of equal length

• Two angles and a side in the same position

Which rule is specifically used for right-angled triangles?

• RHS

• AAS

• SAS

• SSS

For the RHS rule, which two parts of the triangle must be the same?

• All three sides

• Hypotenuse and one other side

• Two sides

• Two angles

If two triangles have two angles and a non-included side equal, which rule can be used to prove congruence?

• AAS

• SAS

• SSS

• RHS
