Across
- 3. when a pair of corresponding angles have equal measures between two pairs of proportional corresponding sides, the two triangles must be similar
- 6. same shape and size
- 7. a transformation that maintains the shape of a figure but multiplies its dimensions by a chosen factor
- 8. a shape with four equal and straight sides and four right angles
- 10. a quadrilateral with one pair of parallel sides
- 13. a line segment that has both endpoints on a circle
- 15. the three sides of two triangles are all corresponding and proportional; are similar
- 17. the amount each side of a figure is multiplied by when the figure is proportionally enlarged or reduced in size.
- 18. the set of points equidistant from a central point
- 19. all the outcomes in the sample space that are not in the original event
- 20. (of two events) the event in which the first event or the second event (or both) occur
Down
- 1. a polygon with four sides
- 2. a line that is perpendicular to a circle's radius
- 4. the distance from the edge of a circle to the center of a circle
- 5. The distance from one point on a circle through the center to another point on the circle
- 6. an angle in a circle with its vertex at the center of the circle
- 9. when two pairs of corresponding angles have equal measures, the two triangles must be similar; since the third pair of angles must also be equal
- 11. (of two events) is the event in which both the first event and the second event occur
- 12. a quadrilateral with four right angles
- 14. a quadrilateral with all sides of equal length
- 16. two lines that intersect outside of a circle and form an angle
