What does the SAS Congruence Theorem say?
A. if a triangle has an angle between two congruent sides, then it is isosceles.
B. if two triangles have one pair of congruent angles between two pairs of congruent sides, then the triangles are congruent.
C. if two triangles have one pair of congruent angles, and two pairs of congruent sides. Then the triangles are congruent.
D. if two triangles have one pair of congruent angles, and at least one pair of congruent sides, then the triangles are congruent.
