Question

how to prove congruency class 8​

Answer 1

Answer:

proving congruency

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 all 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 HL.
