  2. True/False • The three basic building blocks of geometry are point, line, plane.

  3. True/False • The ray through point P from point Q is written in symbolic form as .

  4. True/False • The vertex of angle PDQ is point P.

  5. True/False • The symbol for perpendicular to is .

  6. True/False • An acute angle is an angle whose measure is more than 90°.

  7. True/False • If intersects at point P, then and are a pair of vertical angles.

  8. True/False • If the sum of the measure of two angles is 180°, then the two angles are complementary.

  9. True/False • If two lines are parallel to the same line, then they are parallel to each other.

  10. True/False • If two parallel lines are cut by a transversal, then the alternate interior angles are congruent.

  11. True/False • If a point is equidistant from the endpoints of a segment, then it must be the midpoint of the segment.

  12. True/False • If the sum of the measure of two angles is 180°, the two angles are vertical angles.

  13. True/False • Inductive reasoning is the process of showing that certain statements follow logically from accepted truths.

  14. True/False • In a geometric construction, you use a protractor and a ruler.

  17. Number Patterns • If at a party there are a total of 741 handshakes and each person shakes hands with everyone else at the party exactly once, how many people are at the party?

  18. Number Patterns • If 28 lines are drawn on a plane, what is the maximum number of points of intersection possible?

  19. Number Patterns • If a whole bunch of lines (no two parallel, no three concurrent) intersect in a plane 2926 times, how many lines are a whole bunch?

  20. Number Patterns • If in a 54-sided polygon, all possible diagonals are drawn from one vertex, they divide the interior of the polygon into how many regions?

  21. Number Patterns • How many sides does the polygon have if all possible diagonals drawn from one vertex divide the interior of the polygon into 54 regions?
