which rule explains why these triangles are similar?\nsss\nsas\naa\nnone of the above; the triangles cannot be proven similar
Answer
Explanation:
Step1: Identify given angles
We are given that $\angle E = 30^{\circ}$ and $\angle R=30^{\circ}$. Also, assume the right - angled angles $\angle D=\angle Q = 90^{\circ}$.
Step2: Recall similarity rules
The AA (Angle - Angle) similarity rule states that if two angles of one triangle are equal to two angles of another triangle, then the two triangles are similar. Here we have two pairs of equal angles.
Answer:
C. AA
