  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?

    • Quadrilateral
    • 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.
  30. What is this shape?

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