Avg score: 79% • Most missed: “From the given diagram below, what can be said about two triangles ABC and PQR?”

Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.

These triangles can be slides, rotated, flipped and turned to be looked identical. If repositioned, they coincide with each other.
