Across
- 2. the point where three bisectors of the interior angles of a triangle intersect
- 8. having all its sides of the same length.
- 11. at equal distances
- 13. joining two opposite corners of a square, rectangle, or other straight-sided shape.
- 14. the middle value in a set of data
- 15. divides the opposite side into two parts proportional to the other two sides of the triangle.
- 17. a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.
- 18. a special case of a parallelogram
Down
- 1. having equal angles.
- 3. a line that bisects another line segment at a right angle, through the intersection point.
- 4. opposite sides are parallel.
- 5. the point where the perpendicular drawn from the vertices to the opposite sides of the triangle intersect each other
- 6. he arithmetic mean position of all the points in the surface of the figure.
- 7. a line that passes through two very specific points on a triangle: a vertex, or corner of a triangle, and its opposite side at a right, or 90-degree, angle
- 9. a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
- 10. the point at which the three perpendicular bisectors of the sides of a triangle intersect and which is the same distance from each of the three vertices of the triangle
- 12. a quadrilateral with only one pair of parallel sides.
- 16. plane figure with four equal straight sides and four right angles.
