Similar Triangles

4. Types of angles that add up to equal 180 degrees, are on the interior of two parallel lines and on the same side of the transversal.
5. The similarity theorem that states if two sides of one triangle are proportional to two sides of a second triangle, and the included angles are congruent, then the two triangles are similar.
7. The similarity theorem that states if two angles of one triangle are congruent to two angles of another triangle, the the triangles are similar.
8. The similarity theorem that states the altitude to the hypotenuse of a right triangle divides the triangle into two triangles that are similar to the original triangle and to each other.
9. Types of angles that are across the vertex from each other.
12. Two figures that have the same shape, but different size.
13. When a pre-image is enlarged or reduced.
14. A property that states if two shapes, angles, or lines are congruent to a third, then they are congruent to each other.

1. Types of angles that are equal to each other, are inside a set of parallel lines, and are on the alternate side of the transversal.
2. A property that states that a shared shape, side, or angle is congruent to itself.
3. The value a pre-image is multiplied by to create an image.
6. The theorem that states the sum of all interior angles of a triangle is 180 degrees.
10. Types of angles that are equal to each other, are on the same side of the transversal, and in the same location on each parallel line.
11. The similarity theorem that states if the corresponding sides of two triangles are proportional, then the triangles are similar.
