  1. 3. True/False? All congruent figures are similar
  2. 4. Abbreviation for the proof about Corresponding Parts of Congruent Triangles
  3. 6. The triangle ___ theorem state: If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides the two sides of the triangle proportionally
  4. 8. This theorem, a^2 + b^2 = c^2, may be used to determine the length of a segment on the coordinate plane
  5. 9. If the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the triangles are congruent
  6. 11. If two angles and a non-included side of one triangle are congruent to two angles and a non-included side of another triangle, then the triangles are congruent
  7. 12. If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent
  8. 14. ___ angles are formed by perpendicular lines
  9. 17. Corresponding angles of similar figures are ___
  10. 19. If a triangle is ___, then is equiangular as well
  11. 21. If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent
  12. 24. This triangle similarity theorem states: If two sides of one triangle are proportional to two sides of another triangle, and their included angles are congruent, then the triangles are similar

  9. 18. This angle is formed by the intersection of two leges of an isosceles triangle
  10. 20. If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent
  11. 22. This triangle similarity theorem states: If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar
  12. 23. True/False? All similar figures are congruent
  13. 24. The triangle similarity theorem states: If three sides of one triangle are proportional to three sides of another triangle, then the triangles are similar.
  14. 27. If the scale factor is between 0 and 1, a dilation will result in a(n) reduction
  15. 28. This type of transformation results in similar figures and makes a figure larger or smaller with respect to a fixed point
