1. GEOMETRY Physical and Geometric Solids

2. - the branch of mathematics that is concerned with the properties and relationships of: - points, lines, angles, curves, surfaces, and solids. - The visual study of shapes, sizes, patterns, and positions. What is Geometry?

3. Basic Concepts of Lines, Rays, and Angles.

4. Lines! Different Types: Line Line Segment Ray Perpendicular Parallel Intersecting

5. Line Has no beginning or end. Continues indefinitely in both directions. Can be illustrated by drawing arrows at each end.

6. Line Segment Has a beginning point and an end point. Line segments on a shape are called sides. Can be found in many shapes.

7. Ray Has a beginning point but no end point.

8. Lines in the same plane that do not intersect or cross each other. Parallel

9. Two or more lines that meet at a point. Intersecting

10. Perpendicular lines form a right or 90 degree angle. Perpendicular

11. Made up of two rays with the same start point. The start point is called the vertex. The two rays are called the sides of the angle. Angles

12. A Protractor. Measure Angles with…

13. Zero Angles Right Angles Acute Angles Obtuse Angles Straight Angles Supplementary Angles Complimentary Angles Different Angles

14. PLANE FIGURES!

15. Plane Figure : A two-dimensional shape (2D). A shape on a plane. Includes points, lines, polygons, circles, triangles, hexagon, pentagons, etc. A plane figure is any set of points on a plane. Definition

16. Quadrilateral - a plane figure having four sides and four angles. Parallelograms - a quadrilateral having both pairs of opposite sides parallel to each other. Introduce Terms

17. Space Figures!

18. Space figures are three dimensional figures. Faces: Side of the space figure Edges: Where two faces meet Vertex or Vertices: the corners of the space figures EDGE FACE VERTEX Space Figures!
