Across 1. The sum of 2 angles that equal to 90°. 6. Two lines in the same plane that never intersect. 8. A triangle that none of the sides are congruent. All different measurements. 10. The point that divides a line in two. 12. A line segment connecting a vertex to the line containing the opposite side and perpendicular to that side. 13. A 5 side polygon. 14. A 6 side polygon. 15. A regular 4 side polygon. 16. A 8 side polygon. 17. A 3 side polygon. 18. Specifies only location; it has no length, width, or depth. Usslly marked as a dot. 19. A line that starts with a end point. 20. A 2 demensional figure with. Most have segments, most be closed, and each segment much touch 2 other segments 1 at each end point.

Down 2. The point were two lines intersect and make a 90° angle. 3. A ray that cuts the angle exactly in half, making two equal angles. 4. When a side, angle, or figure is similar to another. Ussally shown with tick marks. 5. A flat 2 demension object the continues infinatelly in all directions. 7. The sum of 2 angles that equal to 180°. 9. A polygon with exactly four sides. 11. Only 1 demension; no length.
