Questions and Answers
  • 1. 
    Any side of a parallelogram perpendicular to an altitude.
  • 2. 
    In a trapezoid, either of the two parallel sides.
  • 3. 
    In a trapezoid, the pairs of angles at the ends of either base.
  • 4. 
    In a quadrilateral, a segment joining nonadjacent vertices.
  • 5. 
    A trapezoid in which the legs are congruent.  Both pairs of base angles are congruent and the diagonals are congruent.
  • 6. 
    A quadrilateral with exactly two distinct pairs of adjacent congruent sides.
  • 7. 
    One of the nonparallel sides of a trapezoid.
  • 8. 
    The segment joining the midpoints of the legs.
  • 9. 
    A quadrilateral in which both pairs of opposite sides are parallel.  Any side may be called a base.  For each base, a segment called an altuitude is perpendicular to the base.
  • 10. 
    A four sided polygon.
  • 11. 
    A quadrilateral with four right angles.
  • 12. 
    A quadrilateral with all four sides congruent.
  • 13. 
    A quadrilateral with four right angles and four congruent sides.
  • 14. 
    A quadrilateral that has exactly one pair of parallel sides, called bases.  The nonparallel sides are called legs.  The pairs of angles with their vertices at the endpoints of the same base are called base angles.  The line segment joining the midpoints of the legs is called the median.  An altitude is a segment perpendicular to the lines containing the bases and having its endpoints on these lines.
  • 15. 
    A perpendicular segment from the line containing the base to the highest point of the figure.  For a regular figure with an odd number of sides, this will be the vertex opposite the base.  For a triangle, the altitude may be completely outside the figure except at the vertex.  For a regular figure with an even number of sides, any perpendicular segment between the base and the segment opposite and parallel to the base.  For an irregular figure, the highest point of the figure may be either a vertex or a segment parallel to the base.
  • 16. 
    A segment from the center of a regular polygon perpendicular to one side at its midpoint.
  • 17. 
    Generally, the side upon which a figure is supposed to rest, which can be any side.  In an isosceles triangle, the side opposite the vertex angle.  In a trapezoid, either of the parallel sides.
  • 18. 
    The common center of the inscribed and circumscribed circles of the regular polygon.
  • 19. 
    An angle formed by two segments drawn to consecutive vertices of a regular polygon from its center.
  • 20. 
    A figure or portion of a figure in which a line can be drawn connecting a side of the figure and another point on the interior of the figure, or containing two points on the figure and a point outside the figure but coplanar to the figure.
  • 21. 
    A figure or portion of a figure in which no line can be drawn connecting a side of the figure and another point on the interior of the figure, nor containing two points on the figure and a point outside the figure but coplanar to the figure.
  • 22. 
    A probability expressed as a proportion of length, area, or volume.
  • 23. 
    The length of an altitude of a figure.
  • 24. 
    A closed figure formed by three or more noncollinear coplanar segments, called sides, that intersect exactly two others, but only at their common endpoints, called vertices.
  • 25. 
    The distance from the center of a regular polygon to any of its vertices.
