  1. 1. The distance from the center of a circle to any point on its circumference.
  2. 3. A perfect round ball. A sphere is a closed solid bounded by a surface on which all points are equidistant from a central point called the center.
  3. 5. A planar surface of a solid figure.
  4. 7. The side opposite the right angle in a right triangle.
  5. 9. Intuitively speaking, curved outward or toward the eye.
  6. 14. An angle with a measure between 0° and 90°.
  7. 16. An angle that measures 90° or /2 radians. It is the angle between two perpendicular lines such as the corner of a square or two perpendicular planes such as the wall and the ground.
  8. 17. Two lines that intersect at right angles.
  9. 19. Also called half-line. It is a straight line that extends from a point.
  10. 20. A pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes.
  11. 21. An initial proposition or statement that is generally accepted as true without proof (self-evident truth) and from which further statements, or theorems, can be derived by using logical deduction.
  12. 22. A polyhedron with two parallel, congruent polygons being its bases and all the other faces being parallelograms.
  13. 25. One of the two pairs of equal angles formed when two straight lines intersect each other.
  14. 26. A three-dimensional figure bounded by plane polygonal faces. The point at which three or more faces meet is called a vertex. A line along which two faces meet is called an edge.
  15. 28. Two angles that add up to 180°.
  16. 29. Two rays sharing a common endpoint.
  17. 31. A number in a sequence or the numerator or denominator of a fraction.
  18. 32. A solid formed by rotating a right triangle around one of its legs.
  19. 33. When at least one of the interior angles of a polygon is greater than 180°.
  20. 38. Two angles that share the same vertex and have one side in common between them.
  21. 39. Lying on the same straight line.
  22. 40. An angle that is between 90° and 180°.
  23. 41. A straight line or a plane that divides a line, a plane, an angle, or a shape into two equal parts.
  24. 42. Two or more straight coplanar lines that do not intersect.
  25. 43. The geometric figure formed by two points.
  26. 45. A unit of measure used to measure the magnitude of an angle, equal in magnitude to 1/360 of a complete revolution.

  1. 2. A line segment that passes through the center of a circle and has its two endpoints on the circle. It also represents the length of such a line segment.
  2. 4. A plane figure bounded by three or more straight-line sides.
  3. 6. An additional geometric figure that is constructed to assist in solving a problem or producing a proof.
  4. 8. A straight line along which two faces of a solid meet.
  5. 9. The boundary line of a circle or the length of such a boundary line.
  6. 10. A pair of adjacent angles formed by intersecting lines.
  7. 11. Two acute angles that add up to 90°.
  8. 12. In plane geometry, when one figure fits exactly on top of the other through simple translation and/or rotation.
  9. 13. The point on a line segment that divides the given line segment into two congruent parts.
  10. 15. A can-shaped solid figure.
  11. 18. A solid figure with one face a polygon (the base) and the other faces being triangles that all share the same vertex.
  12. 20. Points or lines that all lie in the same plane.
  13. 23. Also called non-coplanar lines. They are straight lines that are neither parallel, nor intersecting. They lie in different planes.

  18. 34. Two things that are located or facing directly across.
  19. 35. Part of a line between two points called endpoints.
  20. 36. The length of the boundary around a shape or a figure.
  21. 37. A general conclusion proposed to be proved upon the basis of certain given hypotheses or assumptions; or, a general conclusion that has been proved, e.g., Pythagorean Theorem, Binomial Theorem, Fundamental Theorem of Algebra, etc.
  22. 41. 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.
  23. 42. The geometric figure formed at the intersection of two distinct lines.
  24. 44. The surface included within a closed figure, measured by the number of square units needed to cover the surface.
