Question

Can any explain the congruence theorem for triangles?

Answer 1

if you have 3 equal parts, not including 3 equal angles, you have equal (congruent, identical, same) triangles

Answer 2

what do you mean by 3 equal parts?

Answer 3

take 3 parts of one triangle, and compare them to the same 3 parts of the other triangle; if the comparisons are equal, then the triangles are congruent. This of course only holds of you are not comparing all 3 angles

Answer 4

you have 6 parts entotal for any given triangle; 3 sides and 3 angles.
