Geometry

1. an idealized geometrical model of light or other electromagnetic radiation
3. a primitive notion that models an exact location in space, and has no length, width, or thickness
5. It has four equal sides and four equal angles
7. a simple quadrilateral with two pairs of parallel sides
9. the measure of a region's size on a surface
11. when two objects have the same shape and size
14. It is a geometric space in which two real numbers are required to determine the position of each point

1. a quadrilateral whose four sides all have the same length
2. the perimeter of a circle or ellipse.
4. a point where two or more curves, lines, or edges meet
6. a four-sided polygon
8. a quadrilateral that has at least one pair of parallel sides
10. A figure formed by two rays
11. a prism with a circle as its base
12. any of the line segments from a circles center to its perimeter
13. a three-dimensional geometric shape that tapers smoothly from a flat base to a point
