Geometry Vocab!

4. A Specific location in space with no dimensions, represented by a dot and labeled with a capital letter.
6. A part of a line that starts at one endpoint and extends infinitely in one direction.
7. The total distance around the outside of a polygon, calculated by adding the lengths of all sides.
9. Segment A part of a line that has two endpoints; it is finite in length.
10. A straight, one-dimensional figure that extends infinitely in both directions; defined by two points or a lowercase letter.
11. A polygon with three sides and three angles
12. The measure of the space inside a shape, calculated differently for various polygons (e.g., base times height over 2 for triangles).
14. Two figures that have the same shape but may differ in size; corresponding angles are equal, and corresponding sides are proportional.
16. The branch of mathematics that studies the properties and relationships of points, lines, shapes, and spaces.

1. An angle that measures more than 90 degrees but less than 180 degrees.
2. Two figures or shapes that are the same size and shape; they can be superimposed over one another.
3. A polygon with four sides and four angles.
5. A shape consisting of all points in a plane that are equidistant from a central point, known as the radius.
8. The figure formed by two rays that share a common endpoint, measured in degrees.
13. An angle that measures exactly 90 degrees.
15. An angle that measures less than 90 degrees.
