Two triangles are congruent if and only if all corresponding angles and sides are congruent. That is a lot of work!!
These are congruent because angle A = angle D, Angle B = angle E, angle C = angle F, side AC = side DF, Side AB = side DE, and side CB= side FE.
Please tell me there is an easier way!!

Flipping, rotating, or translating a triangle is not going to change its shape or size.
All those angles will be the same. All those sides will be unchanged as well. |
