Answer:
B. show that the two triangles satisfy the ASA Congruence criterion.
Step-by-step explanation:
In the diagram given, two angles (30° and 120°) and an included side length (1.5 in.) of one triangle are equal or congruent to the corresponding two angles (30° and 120°) and an included side length (1.5 in.) of the other.
The ASA Congruence Theorem states that two triangles are congruent if two angles and an included side length of a triangle is equal to that of the corresponding two angles and side length of the other.
Therefore, Akira's claim can be proven by showing that the two triangles satisfy the ASA Congruence criterion.
