Across
  1. 3. Parallel Postulate- through any given point not on a line there passes exactly one line parallel to that line in the same plane.
  2. 8. the point on a line that is at an equal distance from either end
  3. 9. the amount of space that a substance or object occupies
  4. 12. enlargement of an object
  5. 13. Similarity- Two shapes are Similar when one can become the other after a resize, flip, slide or turn
  6. 15. a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
  7. 16. Theorem- the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse
  8. 17. Sum Theorem- the sum of interior angles of a triangle is 180°.
  9. 18. Measurement- a mathematical method used to find unknown measurements of objects that are difficult to measure
  10. 23. a solid shape that is bound on all its sides by plane faces
  11. 24. changing the size of an object without changing its shape
  12. 25. a type of transformation where we change the size of the original shape to make it bigger or smaller by multiplying it by a scale factor
  13. 26. A three dimensional object.
  14. 27. Factor- the ratio between the scale of a given original object and a new object
  15. 28. any smooth curve joining two points
Down
  1. 1. Similar triangles- used to prove that two triangles are similar or congruent
  2. 2. distance around the edge of a circle
  3. 4. A line segment that goes from one corner to another, but is not an edge.
  4. 5. Space Figures- Two figures are said to be similar if they are the same shape
  5. 6. Mean Theorem- appears in two popular theorems regarding right triangles
  6. 7. distance from the center to the circumference of a circle
  7. 10. terms of pi- xπ where x is whatever number you come up with, and π is simply a placeholder for pi's value
  8. 11. Triangles- same corresponding angle measures and proportional side lengths.
  9. 12. the perpendicular drawn from the vertex of the triangle to the opposite side
  10. 14. a three-dimensional figure.
  11. 19. to the rewriting of an expression into a simpler form
  12. 20. formula- Algebraic expression that gives the distances between pairs of points in terms of their coordinates
  13. 21. the image of a function is the set of all output values it may produce
  14. 22. Right Triangle Theorem- If the altitude is drawn to the hypotenuse of a right triangle, then the two triangles formed are similar to the original triangle and to each other
  15. 26. he area between two radiuses and the connecting arc of a circle
