    • Shape Recognition
      Let’s start off real basic! Can you name these geometric shapes? Go ahead and label them!
      Diamond
      or Rhombus
      Pentagon
      Square
      Circle
      Trapezoid
      Triangle
    • Properties of Basic Shapes
      Now let’s quickly go over some properties of basic shapes. . .
    • Triangles
      Triangles can be distinguished by their _____ and their ______
      sides
      angles
      All six of these characteristics can be combined. . . (see the next slide)
    • Classifying Triangles
      Since triangles are distinguished between their sides and angles we can also categorize them by their sides and angles.
      Can you place these triangles accordingly in the diagram?
    • Quadrilaterals
      Q: Does anyone know what a quadrilateral is?
      D: A quadrilateralis a four sided figure.
      Q: Can you think of a geometric shape that would fit this description?
      These are just some examples.
      Square
      Parallelogram
      Diamond
      Trapezoid
      Rectangle
      Review: Quadrilaterals∙ By: EnchantedLearning.com
    • Classifying Quadrilaterals
      Quadrilaterals can best be classified by their ____________. The Venn Diagram below demonstrates how the quadrilaterals can be classified accordingly.
      parallel lines
      0 = Zero parallel lines
      1 = One set of parallel lines
      2= Two set of parallel lines
      2
      2
      2
      Parallelogram
      Diamond
      1
      0
      Rectangle
    • Regular Polygons
      Q: Does anyone know what a regular polygon is?
      D: A regular polygon is a polygon where all the sides are the same and all the interior angles are the same.
      Q: Can you think of a geometric shape that would fit this description?
      3-sided
      regular polygon
      4-sided
      regular polygon
      5-sided
      regular polygon
      6-sided
      regular polygon
      8-sided
      regular polygon

    • Line Symmetry
      Q: Does anyone know what line symmetry is?
      D. Line symmetry is when one half of an image is the mirror image of the other half
      Sometimes shapes/figures can have more than one line of symmetry.
      This is an example of a pentagon
      having line symmetry
      See if you can figure out anymore lines on symmetry between either the pentagon or the hexagon

    • Rotational Symmetry
      Q: Does anyone know what rotational symmetry is?
      D. Rotational symmetry is when there is a center point around which the object is turned a certain number of degrees and the object still looks the same. That is it matched itself a number of times while it is being rotated. (Webquest)
      Review: Rotational Symmetry∙ By: Webquest
    • Geometry in the Every Day
      Geometric shapes can be found everywhere. Here are some examples of geometric shapes in the nature
      Lines symmetry can also be found everywhere. Here are some examples of geometric shapes in the nature
