Across
- 3. a line that touches a circle at exactly one point
- 6. a segment that passes through the center of a circle with endpoints on the circle
- 8. the new figure created after a transformation is applied to the original figure
- 9. a triangle congruence rule stating triangles are congruent if all three sides are equal
- 13. a segment from the center of a circle to a point on the circle
- 14. a triangle with at least two equal sides
- 15. an angle whose vertex is at the center of a circle
- 18. a triangle with three equal sides and three equal angles
- 19. figures that have the same size and shape
Down
- 1. opposite angles formed when two lines intersect that are always equal
- 2. when a figure can be divided into parts that are mirror images of each other
- 4. lines in the same plane that never intersect
- 5. a transformation that flips a figure across a line creating a mirror image
- 7. an angle whose vertex lies on the circle and whose sides intercept an arc
- 10. a segment whose endpoints lie on a circle
- 11. a curved portion of the circumference of a circle
- 12. the point exactly halfway between the endpoints of a segment
- 16. a transformation that slides a figure without changing its size shape or orientation
- 17. a triangle congruence rule stating triangles are congruent if two sides and the included angle are equal
- 20. a transformation that turns a figure around a fixed point by a certain angle
