2. Point: The geometric figure formed at the intersection of two lines.

3. Line (segment): All points between two given points (including the given points themselves).

4. Plane: A flat surface extending in all directions.

5. Angle: Two rays sharing a common endpoint.

6. Perpendicular lines: Lines that intersect in a 90 degree angle.

7. Parallel Lines: Two distinct coplanar lines that don’t intersect.

8. Triangle: A polygon with three sides.

9. Right Triangle: A triangle which has a right (90 degree) interior angle.

10. Pentagon: A polygon with five sides.

11. Hexagon: A polygon with six sides.

12. Square: A rectangle with all four sides of equal length (90 degrees each).

13. Rectangle: A quadrilateral with four congruent angles (90 degrees).

14. Trapezoid: A quadrilateral which has a pair of opposite sides which are parallel.

15. Parallelogram: A quadrilateral with with two pairs of parallel sides.

16. Circle: The locus of all points that are a fixed distance from a given point.

17. Cylinder: A 3D geometric figure with parallel congruent bases.

18. Sphere: A 3D solid consisting of all points equidistant from a given point.

19. Acute triangle A triangle for which all interior angles are acute.

20. Obtuse triangle A triangle which has an obtuse angle as one of its interior angles. This is a kitchen tile.

21. octagon A polygon with eight sides.
