The base is different. A rect. pyramid has a rectangle as a base. Because the sides are different length for a rectangle, the triangles will not all be congruent (equal). A square pyramid has a square as the base. All sides of the square are the same length, so all the triangular sides of the pyramid will be congruent.
No, it means they have either 2 sides and 1 angle congruent, 2 angles congruent, 2 angles and a side congruent, or 3 sides congruent.
2 pairs of consecutive congruent sides
