2. Geometry A Presentation of Lines and Shapes Presented By: Ebony Fails

3. line A line is the straight path connecting two points and extending beyond the points in both directions

4. line segment All points between two given points (including the given points themselves).

5. ray A part of a line starting at a particular point and extending infinitely in one direction.

6. right angle A right angle is a 90° angle A carpenter’s square forms a right angle

7. acute angle An angle that is less than 90°

8. obtuse angle An angle that has measure more than 90° and less than 180°.

9. intersecting lines Intersecting line are lines that cross each other.

10. parallel lines Lines that do not cross or touch are parallel.

11. perpendicular lines Lines that meet at a point and form 90° angles.

12. Cone A three dimensional figure with a single base tapering to an apex.

13. Cylinder An object or shape with straight sides and circular ends of equal size.

14. rectangular prism A solid (3-dimensional) object which has six faces that are rectangles. It is a prism because it has the same cross-section along a length.

15. Sphere A globe similar to the shape of a circle.

16. Pyramid A polyhedron with a polygonal base and lateral faces that taper to an apex.

17. cube A regular polyhedron for which all faces are squares.
