Across
  1. 3. A location that is denoted by a capital letter. It has no size and is shown as a dot.
  2. 4. A flat, two-dimensional surface. They can extend horizontally or vertically.
  3. 5. The middle point of a circle. The point of a circle that is equally distant from all points of the circle.
  4. 6. A transformation in which a plane figure turns around a fixed center point. The center of rotation is fixed and all other points rotate around it.
  5. 8. A theorem used when one triangle side length is missing. Two sides are squared and added/subtracted to determine the missing side length.
  6. 9. A tringle that has two sides of equal length. Two congruent legs and sides.
  7. 15. A triangle that has three congruent sides. Three angles of equal length.
  8. 17. A transformation that produces an image that is the same shape as the original. However, the image is a different size based on a scale factor.
  9. 19. A point where all three medians of a triangle intersect. The medians are the segments that connect a vertex to the midpoint of the other side.
  10. 20. A straight line segment. Both endpoints of the line segment lie on the circle.
Down
  1. 1. A line that touches a point at a curve. It does not cross or intersect the curve.
  2. 2. A triangle that has three unequal sides. No equal angles.
  3. 7. A transformation in which an object moves a certain distance. The initial figure is congruent to the final image and distance and orientation is preserved.
  4. 10. A line that passes through a circle. It intersects two points on the curve.
  5. 11. Any straight line segment. It passes through the center of the circle and its endpoints lie on the circle.
  6. 12. A section of a circle. The portion of a disk enclosed by two radii and an arc.
  7. 13. A transformation in which each point of the pre-image has an image that is the same distance from the line of reflection. Can be described as a ‘flip’ over the line of reflection.
  8. 14. A line segment on a circle. It extends to the perimeter of the circle from the center point.
  9. 16. A line from the center of a polygon at right angles. It extends from the center to any of its sides.
  10. 18. A straight one-dimensional figure having no thickness. It extends indefinitely in two directions.
