  1. 1. Lines are____if they lie in the same plane, and are the same distance apart over their entire length
  2. 3. is a perfectly round geometricaland circular object in three-dimensional space, such as the shape of a round ball.
  3. 5. Often referred to as the right cone. A cone is a solid formed by rotating a right triangle around one of its legs.
  4. 6. The side opposite the right angle in a right-angled triangle
  5. 8. Lying on the same straight line.
  6. 9. A straight line or a plane that divides a line, a plane, an angle, or a shape into two equal parts.
  7. 11. meets or crosses it at right angles (90°).
  8. 15. A precise location or place on a plane. Usually represented by a dot
  9. 19. A straight line going through the center of a circle connecting two points on the circumference.
  10. 20. Polygons that have all corresponding sides and all corresponding angles congruent.
  11. 23. sides are triangles which meet at the top (the apex).It is a polyhedron.
  12. 25. A pair of non-adjacent angles formed by the intersection of two straight lines
  13. 29. A solid with flat faces
  14. 31. If the sum of the measures of two angles is 90°, the angles are called complementary. Whenever two angles are complementary, each angle is said to be the complement of the other angle.

  20. 44. any angle over 90 degrees
  21. 46. A point B that lies on the line connecting two points A and C and has one of the two points on each side of it.
  22. 47. A geometrical object that is straight, infinitely long and infinitely thin.

  1. 2. An angle with a measure between 0° and 90°.
  2. 3. Two Angles are ____if they add up to 180 degrees.
  3. 4. A line from the center of a circle to a point on the circle. The distance from the center of a circle to a point on the circle.
  4. 5. An additional geometric figure that is constructed to assist in solving a problem or producing a proof.
  5. 7. Two rays with a common endpoint that point in opposite directions and form a straight line
  6. 10. The distance around the edge of a figure or shape. For example it is the sum of the lengths of each side ofpolygon. For circles and ellipses, it is called the circumference.

  12. 18. In plane geometry, when one figure fits exactly on top of the other through simple translation and/or rotation, then these two figures are congruent.
  13. 20. speaking, curved outward or toward the eye. A convex curve is a set of points any of whose chords do not include any point that is not in the set.
  14. 21. a general proposition not self-evident but proved by a chain of reasoning; a truth established by means of accepted truths.
