4. shape shapes whose angles are congruent and side lengths are proportional (equal scale factor)
5. a linear measurement of the distance around a circle
6. Surface Area sum of all the areas of the surfaces
8. the distance around an object, found by adding all sides
9. the measurement attribute that describes the number of square units a figure or region covers

1. a line segment drawn from the center of a circle to any part of the outer edge (halfway across)
2. the amount of space inside of a 3D object
3. a line segment whose endpoints are on the circle and passes through the center of circle (all the way across)
5. of equal measure, having exactly the same size and same shape
7. Surface Area sum of all the areas of the surfaces expect for the base or bases
