1. what is this called?

• Point
• A POINT is represented by a dot.
2. Define the word GEOMETRY
• The study of space (distance).
• Geometry is a branch of mathematics which involves the measuring of shapes. The word Geometry actually means "to measure the earth."
3. What is this called?

• Line Segment
• A LINE SEGMENT is represented by a group of points having tow endpoints. LINE SEGMENTS of the same length are congruent.
4. What is this called?

• Line
• A LINE is represented by a group of points having no endpoints.  A line extends indefinitely in two opposite directions.
5. What is this called?

• Ray
• A RAY is represented by a group of points having one endpoint. A RAY extends indefinitely in one direction.
6. What is this called?

• Angle
• An ANGLE is two rays that share a common endpoint.  The common endpoint is called the vertex.
7. What is this called?

• Intersecting Lines
• INTERSECTING LINES are lines that cross each other at some point.
8. What are these lines called?

• Perpendicular Lines
• PERPENDICULAR LINES are intersecting lines that form four right angles.
9. What is a PLANE?
A PLANE is represented by a smooth, flat surface that has no thickness and extends indefinitely in all directions.
10. What are these lines called?

• Parallel Lines
• PARALLEL LINES are lines that never intersect.
11. What are these shapes?

• Simple Closed Figures
• SIMPLE CLOSED FIGURES do not have a point of intersection.
12. What are these shapes?

• Similar Figures
• SIMILAR FIGURES have the same shape but not the same size.
13. What are these shapes?

• Congruent Figures
• CONGRUENT FIGURES have the same size and shape.
14. What are these shapes?

• Polygons
• A POLYGON is a simple closed figure made up of line segments.
15. what is this shape?

• Triangle
• A TRIANGLE is a polygon with 3 sides.
16. What is this shape?

• A QUADRILATERAL is a polygon with 4 sides.
17. What is this shape?

• Parallelogram
• A PARALLELOGRAM is a quadrilateral having opposite sides which are parallel.
18. What is this shape?

• Rectangle
• A RECTANGLE is a parallelogram having 4 right angles. The box in the corner means perpendicular lines forming a right angle.
19. What is this shape?

• Square
• A SQUARE is a rectangle having 4 congruent sides.  The double line segments on each side means they are congruent.
20. What is this shape?

• Rhombus
• A RHOMBUS is a parallelogram having 4 congruent sides.
21. What is this shape?

• Trapezoid
• A TRAPEZOID is a quadrilateral having only 2 sides that are parallel.
22. What is this shape?

• Pentagon
• A PENTAGON is a polygon having 5 sides.
23. What is this shape?

• Hexagon
• A HEXAGON is a polygon having 6 sides.
24. What is this shape?

• Octagon
• A OCTAGON is a polygon having 8 sides.
25. What is this shape?

• Heptagon
• A HEPTAGON is a polygon having 7 sides.
26. What are the points called where the sides of the polygon meet?  (point A, B, C or D)

Vertexes
27. What is the line called that joins two opposite vertexes (line BD)?

• Diagonal
• A DIAGONAL is not a side.
28. What is this shape?

• Heptagon
• A HEPTAGON is a polygon having 7 sides.
29. What is this shape?

• Heptagon
• A HEPTAGON is a polygon having 7 sides.
