1. states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
2. a transformation in which a figure is turned about a fixed point is called a.
3. if one image can be obtained from another by a sequence of transformations and dilations, the images are.
4. a is a transformation that enlarges or reduces a figure by a scale factor.
5. a transformation in which a figure is slid from one position to another without being turned is called a.
6. if one image can be obtained from another by a sequence of rotations, reflections, or translations the images are.
7. a is a transformation in which a figure is flipped over a line.

Explanation:

1. AA Similarity is the concept that if two - angles of one triangle are congruent to two angles of another triangle, the triangles are similar.
2. Rotation is a transformation where a figure is turned about a fixed point.
3. Similar figures can be obtained from one another by a sequence of transformations and dilations.
4. Dilation is a transformation that enlarges or reduces a figure by a scale factor.
5. Translation is a transformation where a figure is slid from one position to another without being turned.
6. Congruent figures can be obtained from one another by a sequence of rotations, reflections, or translations.
7. Reflection is a transformation where a figure is flipped over a line.

Answer:

1. AA Similarity
2. rotation
3. similar
4. dilation
5. translation
6. congruent
7. reflection
