Across
- 5. two triangles are similar whenever two angles of one triangle are congruent to two angles of the other triangle
- 10. 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
- 11. a way to measure objects that are too large to measure using a tape measure or ruler
- 12. when the image of a dilation is smaller than the original figure
- 13. the distance from the center of a circle to the edge of a circle (half the distance of the diameter
- 15. a three dimensional object (having length, width, anf height

- 20. a part of a circle
- 23. a point halfway between the endpoints of a segment
- 26. in a triangle, the segment drawn from a vertex perpendicular to the line containing the opposite side
- 27. the sum of the measures of the angles of a triangle is 180o
- 28. when the image of a dilation is larger than the original figure
- 30. 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 each other
- 31. the distance across a circle through the center
- 32. if the altitude is drawn to the hypotenuse of a right triangle, then measure of the altitude is the geometric mean between the measures of the parts of the hypotenuse
