  1. 7. A line segment from the center of a circle to any point on its circumference.
  2. 8. A polygon with four edges (sides) and four vertices (corners).
  3. 13. A polygon with three edges and three vertices.
  4. 14. A precise location or place on a plane. It has no size, area, or dimension.
  5. 16. A part of a line that is bounded by two distinct endpoints.
  6. 17. The figure is formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
  7. 19. Lines that intersect at a right angle (90 degrees).
  8. 20. A polygon with five edges (sides) and five vertices (corners).
Down
  1. 1. Lines in a plane that do not meet; they are always the same distance apart.
  2. 2. Exactly equal in size and shape. In geometry, it refers to figures or angles that are identical in form.
  3. 3. A flat, two-dimensional surface that extends infinitely in all directions.
  4. 4. In a polygon, the side on which the figure is considered to stand; in a triangle, it is often referred to as the side opposite the altitude.
  5. 5. A perpendicular segment from a vertex to the line containing the opposite side of a polygon, especially in a triangle.
  6. 6. A line segment that passes through the center of a circle and has its endpoints on the circle.
  7. 9. A part of a line that starts at a point and extends infinitely in one direction.
  8. 10. A round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
  9. 11. A property where one half of a figure is a mirror image of the other half.
  10. 12. A plane figure with at least three straight sides and angles, typically having five or more.
  11. 15. A point where two or more curves, edges, or lines meet; in the context of angles and polygons, it is the corner.
  12. 18. A straight one-dimensional figure having no thickness and extending infinitely in both directions.
