Question

1. if two angles in one triangle are equal to two angles in another triangle, then the triangles are similar by ______ similarity.

Explanation:

In geometry, the Angle - Angle (AA) similarity criterion states that if two angles of one triangle are equal to two angles of another triangle, then the two triangles are similar. This is because the sum of angles in a triangle is \(180^{\circ}\). If two angles are equal, the third angle (calculated as \(180^{\circ}-(\text{sum of the two known angles})\)) will also be equal.

Answer:

Angle - Angle (AA)
