Transcript text: Select ALL statements that are true about the triangles. (Do not add stuff to the diagram)
a. $\mathrm{ABC} \cong \mathrm{DCB}$ because of Angle-Side-Angle (ASA)
b. $A B C \cong D C B$ because of Angle-Angle-Angle (AAA)
c. $\mathrm{ABC} \cong \mathrm{DCB}$ because of Side-Side-Side (SSS)
d. $\mathrm{ABC} \cong \mathrm{DCB}$ because of Side-Angle-Side (SAS)
e. $A B C \cong D C B$ because of Angle-Side-Side (ASS)
Solution
Solution Steps
Step 1: Analyze the given information
Triangle ABC has two angles marked congruent to two angles in triangle DCB. Side BC is shared by both triangles and therefore congruent to itself.
Step 2: Determine the congruent triangles
Since two angles and the included side are congruent, the triangles are congruent by the Angle-Side-Angle (ASA) postulate.
