Question

what is the least amount of information that you need to construct a triangle congruent to this one?

Explanation:

Step1: Recall congruence postulates

There are SSS (Side - Side - Side), SAS (Side - Angle - Side), ASA (Angle - Side - Angle), AAS (Angle - Angle - Side) and HL (Hypotenuse - Leg for right - triangles).

Step2: Determine the least amount

The least amount of information is 3 pieces of information which can be three sides (SSS), two sides and the included angle (SAS), two angles and the included side (ASA) or two angles and a non - included side (AAS).

Answer:

3 pieces of information (either SSS, SAS, ASA or AAS)
