Down
- 2. Two shapes are said to be _____ if they are scaled copies of each other, with different sizes
- 3. The angle formed by two perpendicular lines; or the type of angle that is seen at the vertexes of a rectangle
- 4. Describes two lines or planes which face precisely the same direction and never intersect
- 5. A characteristic of a shape or solid where when the solid is either reflected across some line or rotated around some point, it does not move or change because the pieces match up
- 6. A transformation in which all of the vertexes in a shape are rotated around a central point
- 7. A tool used for drawing circles
