What does AA similarity theorem state?

• If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

• If two angles of one triangle are congruent to two sides of another triangle, then the triangles are similar.

• If two sides of one triangle are congruent to two sides of another triangle, then the triangles are similar.

• If two sides of one triangle are congruent to two angles of another triangle, then the triangles are similar.

If two angles of one triangle are congruent to two angles of another triangle, then what can be said about the two triangles?

• The two triangles are parallel.

• The two triangles are similar.

• The two triangles are congruent.

• The two triangles are perpendicular.

What is the significance of the AA similarity theorem in geometry?

• The AA similarity theorem is used to calculate the area of a triangle

• The AA similarity theorem is only applicable to right-angled triangles

• The AA similarity theorem is used to find the sum of the angles in a triangle

• The significance of the AA similarity theorem is that it provides a quick and easy way to determine if two triangles are similar without having to measure all their sides.
