  3. 8. a solid with two parallel bases
  4. 11. distance across the circle through the middle
  5. 13. when the image of a dilation is smaller than the original figure
  6. 14. Two triangles whose vertices can me matched up so that the corresponding angles are equal in measure and the corresponding sides are in proportion
  7. 15. distance around the circle
  8. 16. a solid with a polygon for a base and a signle vertex not in the plane on the base
  9. 18. √[(x₂ - x₁)² + (y₂ - y₁)²]
  10. 20. A way to measure objects that are too large to measure using a tape measure or ruler
  11. 21. the segment drawn from a vertex perpendicular to the line containing the opposite side
  12. 22. A point halfway between the endpoints of a segment
  13. 23. when the image of a dilation is larger than the original figure

  16. 27. the sum of the measures of the angles of a triangle is 180 degrees
  17. 30. if the altitude is drawn to the hypotenuse of a right triangle, then the measure of the altitude is the geometric mean between the measures of the parts of the hypotenuse
Down
  1. 1. a three dimensional object (having length, width, and height)
  2. 2. if the altitude is drawn to the hypotenuse of a right angle, then the two triangles formed are similar to the original triangle and to eachother

  7. 9. a segment of a polygon joining two non consecutive sides
  8. 10. the sum of the measures of the angles of a triangle is 180o
  9. 12. if a line is drawn from a point on one side of a triangle parallel to another side, then it forms a triangle similar to the original triangle
  10. 14. drawing represents an actual object
