geometry

3. a transformation that enlarges or reduces a figure proportionally from a fixed point called the center of dilation
6. a geometric transformation that moves every point of a figure the same distance in the same direction
8. a comparison of two or more quantities, showing their relative sizes
10. if they have the exact same shape but potentially different sizes
11. the middle point of a shape
12. a geometric figure drawn around another figure, touching its points
13. to determine a value or solve a problem by performing mathematical operations

1. a geometric transformation that creates a mirror image of a figure by flipping it across a line
2. a line segment that connects two points on a curve, most commonly a circle
3. straight line segment that passes through the centre of the circle
4. the distance from the center of a circle or sphere to any point on its circumference or surface
5. the total distance around the edge of a circle or any curved shape
7. the length or space between two points or objects
9. a figure is drawn inside another, with its points touching the boundary of the outer figure
14. a continuous segment of a circle's circumference connecting two points
