Across
- 3. a transformation that changes the size of a shape while keeping its shape the same
- 4. a triangle with three acute angles, that means they measure less than 90°.
- 6. lines that never intersect, and they form the same angle when they cross another line.
- 9. the point of a figure that is opposite to and farthest from its base
- 10. a line segment that connects the midpoints of two sides of a triangle
- 11. a ratio that describes how much a shape has been enlarged or shrunk
- 13. a two-dimensional shape with four sides, four vertices, and four angles
- 14. the longest side of a right-angled triangle compared to the length of the base and perpendicular
Down
- 1. a straight line at an angle of 90° to a given line, plane, or surface
- 2. having the same shape and size.
- 4. a ray, segment, or line that divides a given angle into two angles of equal measures
- 5. the shifting of a figure from one place to another without rotating, reflecting or changing its size.
- 7. a theorem stating that in a right triangle, the length of each leg is the geometric mean of the length of the hypotenuse and the segment of the hypotenuse directly below that leg
- 8. a line that crosses two or more lines at different points
- 12. the property that in a right triangle, the altitude drawn from the right angle to the hypotenuse divides the hypotenuse into two segments, and the length of the altitude is the geometric mean of the lengths of those segments
