Question

which rule explains why these triangles are similar?
sss
sas
aa
none of the above; the triangles cannot be proven similar

Explanation:

The AA (Angle - Angle) similarity criterion states that if two angles of one triangle are equal to two angles of another triangle, then the two triangles are similar. In triangle \(RST\) and triangle \(JKI\), \(\angle R = \angle J=51^{\circ}\) and \(\angle T=\angle I = 98^{\circ}\).

Answer:

AA
