  7. 15. triangles whose vertices can be matched up so that the corresponding angles are equal in measure and the corresponding sides are in proportion
  8. 19. If the altitude is drawn to the hypotenuse of a right triangle, then the measure of the altitude is the geometric mean between the measures of the parts of the hypotenuse
  9. 21. Two triangles are similar whenever two angles of one triangle are congruent to two angles of the other triangles
  10. 24. If a line is drawn from a point on one side of a triangle to another side, then it forms a triangle similar to the original triangle

  14. 32. If the altitude is drawn to the hypotenuse of a right triangle, then the two triangles are formed are similar to the original triangle and to each other
Down
  1. 1. In any right triangle, the square of the length of the hypotenuse is equals to the sum of the squares of the lengths of the legs
