  1. 1. This term is a polygon that is equilateral, which has all congruent sides. This term is also equiangular, which has all congruent angles.
  2. 5. These type of angles are two wo coplanar angles with a common side, and a common vertex. Although these theses do not have common interior points.
  3. 6. This is an angle whose vertex is a point on the circle. The sides of this angle also contain chords.
  4. 9. This is a point or line that intersects a segment at its midpoint. It can also be a ray or segment.
  5. 14. These angles are between the two lines and are on the same side of the transversal. These are also known as consecutive interior angles.
  6. 15. This is a straight line or plane that touches a curve or curved surface at a point. Although, if extended does not cross it at that point.
  7. 16. This is a quadrilateral only has 1 pair of parallel. This is also a quadrilateral with two congruent legs.
  8. 19. A triangle in which all three sides are equal. This triangle also has all equal angles, each being 60°.
  9. 20. This part of a circle is a segment that contains the center og the center and whose endpoints are on the circle. The term can also mean the length of this segment.

  1. 2. These angles are angles that lie outside of the two lines. These angles are also on opposite sides of the transversal.
  2. 3. A triangle that has two sides of equal length. This angle also has two congruent angles.
  3. 4. These angles are angles that lie between the two lines. These angles are also on opposite sides of the transversal.
  4. 7. A figure has this if there is an isometry that maps the figure onto itself. A few examples that have this would be a square, rectangle, and an isosceles trapezoid.
  5. 8. This type of point divides a segment into two segments. When the segments are divided, they end up up being congruent to each other.
  6. 10. This term is a part of the circle that is any segment with one endpoint on a circle and the other endpoint at the center of a circle. This term can also mean the length of this segment.
  7. 11. These types of angles when put together make a sum of 90°. For example, this term can be used to describe the angles of 22° and 68°.
  8. 12. These types of angles when put together make a sum of 180°. For example, this term can be used to describe the angles of 157° and 23°.
  9. 13. This term is a polygon with all angles congruent. An example of this term would be a square.
  10. 17. This term is a segment from the vertex of a triangle to the opposite side. This segment must be perpendicular to the segment of the opposite side.
  11. 18. This term is the ratio of the hypotenuse to the shorter side adjacent to an acute angle (in a right-angled triangle). This term is also the reciprocal of a cosine.
