Thanks Ms.Sue!! It has been a LONG time since I posted!!
But when i search a word I didn't understand what it meant. Can anyone help me find a GOOD math dictionary?
You're welcome -- and welcome back!
This should help you.

Sure! Here are the definitions you requested:
1. Point: A point is an exact position or location in space. It has no size or dimensions.
2. Line: A line is a straight path that extends infinitely in both directions.
3. Intersecting Lines: Intersecting lines are lines that cross or meet at a single point.
4. Parallel Lines: Parallel lines are lines that never intersect and are always the same distance apart.
5. Vertical Lines: Vertical lines are lines that go straight up and down when depicted on a plane.
6. Horizontal Lines: Horizontal lines are lines that go straight across from left to right when depicted on a plane.
7. Acute Angle: An acute angle is an angle that measures less than 90 degrees.
8. Obtuse Angle: An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.
9. Right Angle: A right angle is an angle that measures exactly 90 degrees. It forms a perfect "L" shape.
10. Square: A square is a polygon with four equal sides and four equal angles (right angles).
11. Rectangle: A rectangle is a polygon with four right angles, but opposite sides are equal in length.
12. Trapezoid: A trapezoid is a quadrilateral with one pair of parallel sides.
13. Rhombus: A rhombus is a quadrilateral with all four sides equal in length.
14. Pentagon: A pentagon is a polygon with five sides.
15. Hexagon: A hexagon is a polygon with six sides.
16. Octagon: An octagon is a polygon with eight sides.
17. Triangle: A triangle is a polygon with three sides.
18. Circle: A circle is a closed curve where all points on the curve are equidistant from the center point.
19. Chord: A chord is a line segment that connects two points on the circumference of a circle.
20. Radius: The radius is a line segment from the center of a circle to any point on the circumference.
21. Diameter: The diameter is a line segment that passes through the center of the circle and connects two points on the circumference.
22. Cube: A cube is a three-dimensional shape with six equal square faces.
23. Rectangular Prism: A rectangular prism is a three-dimensional shape with six rectangular faces.
24. Cylinder: A cylinder is a three-dimensional shape with two congruent circular bases and a curved surface connecting them.
To gain a deeper understanding or further examples of these concepts, you can refer to math textbooks, online educational resources, or explore interactive geometry apps or websites.
