Identify the given congruent sides

Using the Triangle Congruence Postulates knowledge point

  • One pair of corresponding sides has double tick marks, indicating they are congruent.
  • Another pair of corresponding sides has triple tick marks, indicating they are congruent.

Identify the vertical angles

Using the Vertical Angles Theorem knowledge point

  • The two triangles share a vertex where their lines intersect.
  • The angles opposite each other at this intersection are vertical angles, which are congruent.

Apply the congruence postulate

Using the SAS Congruence knowledge point

  • The congruent vertical angles are located directly between the two pairs of congruent sides.
  • This Side-Angle-Side relationship proves the two triangles are congruent.
