Geometry

3. A geometric shape formed by the group of points that are an equal distance from a point, or center.
4. The amount of space, or number of square units, inside a closed figure.
5. The point where the two sides of an angle intersect.
8. A special constant value that relates the diameter of a circle to its circumference. Pi is used to find the circumference and area of a circle and applies for any circle.
9. The distance from one edge of the circle to the opposite edge that passes through the center.
10. One of two points on a line segment that signifies where the line segment ends.
11. One of the two equal sides in an isosceles triangle.
14. A quadrilateral with opposite parallel sides.
16. A closed shape consisting of line segments that has at least three sides. Triangles, quadrilaterals, rectangles, and squares are all types of polygons.
17. ANGLE AN ANGLE THAT MEASURES MORE THAN 0 DEGREES AND LESS THAN 90 DEGREES
18. The distance from the center to the edge of a circle.

1. A line, line segment, or ray that intersects a circle at two points.
2. A flat surface that extends infinitely in any direction in three dimensions. A plane is represented by a closed four-sided figure.
6. A parallelogram with equal sides, resembles a diamond
7. A section of mathematics that involves the measurements, properties, and relationships of all shapes and sizes of things.
8. A tool that can be used to measure or create an angle.
12. ANGLES THE MESURE OF TWO ANGLES WHICH MEASURE THE SAME
13. A perpendicular line drawn from the highest point in the triangle to the base on the opposite side.
15. A line segment that divides a circle into two segments.
