ðŸŽ¬ Video Tutorial
Congruent Triangles:
Have identical side lengths and angle measures, meaning they match in size and shape.
SideSideSide (SSS) Rule:
If all three sides of two triangles are equal, the triangles are congruent.
SideAngleSide (SAS) Rule:
Two triangles are congruent if they share two equal sides and the angle between them.
AngleSideAngle (ASA) Rule:
Two triangles are congruent if they share two equal angles and the side between them.
RightAngleHypotenuseSide (RHS) Rule:
For rightangled triangles, if the hypotenuse and one other side are equal, the triangles are congruent.
