Two triangles are congruent if they have:
exactly the same three sides and
exactly the same three angles.
But we don't have to know all three sides and al
l three angles ...usually three out of the six is
enough.
There are five ways to find if two triangles are
congruent: SSS, SAS, ASA, AAS and CPCTC.
1.SSS (side, side, side)
2. SAS (side, angle, side)
3. ASA (angle, side, angle)
4. AAS (angle, angle, side)
