CONGRUENT TRIANGLES - 8 STANDARD

Congruence

If two objects are said to be congruent, they should have the same size and shape and it should be coin sided  
when one's trace is placed on the other.

Theorems to determine congruency

SSS Theorem (Side Side Side)

If three sides of a triangle are equal to three sides of another triangle, then these triangles are congruent.

SAS theorem (Side Angle Side)

If two sides and their including angle are equal to two sides and including angle of another triangle,then these triangles are congruent.

SAA theorem (Side Angle Angle)

If two angles and their including side of a triangle are equal to two angles and including angle of another triangle, then these triangles are congruent.

RHS theorem (Right Angle Hypotenuse Side)

If the hypotenuse and one side of a right angled triangle are equal to the hypotenuse and one side of another triangle, then these triangles are congruent.
