To prove the Isosceles Triangle Theorem using a figure, the best strategy is to focus on the properties of the triangle's angles and sides. Start by labeling the two equal sides and their opposite angles. Then, use triangle congruence criteria, such as the Side-Angle-Side (SAS) or Angle-Side-Angle (ASA), to establish that the two triangles formed by drawing a line from the vertex to the base are congruent. This congruence will demonstrate that the base angles are equal, thereby proving the theorem.
