- 13. Properties of Basic Shapes<br />Now let’s quickly go over some properties of basic shapes. . .<br />
- 14. Triangles<br />Triangles can be distinguished by their _____ and their ______<br />sides<br />angles<br />All six of these characteristics can be combined. . . (see the next slide) <br />
- 15. Classifying Triangles<br />Since triangles are distinguished between their sides and angles we can also categorize them by their sides and angles.<br />Can you place these triangles accordingly in the diagram?<br />
- 16. Quadrilaterals<br />Q: Does anyone know what a quadrilateral is?<br />D: A quadrilateralis a four sided figure. <br />Q: Can you think of a geometric shape that would fit this description?<br />These are just some examples.<br />Square <br />Parallelogram <br />Diamond <br />Trapezoid <br />Rectangle <br />Review: Quadrilaterals∙ By: EnchantedLearning.com<br />
- 17. Classifying Quadrilaterals<br />Quadrilaterals can best be classified by their ____________. The Venn Diagram below demonstrates how the quadrilaterals can be classified accordingly.<br />parallel lines<br />0 = Zero parallel lines<br />1 = One set of parallel lines<br />2= Two set of parallel lines<br />2<br />2<br />2<br />Parallelogram <br />Diamond <br />1<br />0<br />Rectangle <br />
- 18. Regular Polygons<br />Q: Does anyone know what a regular polygon is?<br />D: A regular polygon is a polygon where all the sides are the same and all the interior angles are the same. <br />Q: Can you think of a geometric shape that would fit this description?<br />3-sided <br />regular polygon<br />4-sided<br />regular polygon<br />5-sided <br />regular polygon<br />6-sided <br />regular polygon<br />8-sided <br />regular polygon<br />Review: A Study of Regular Polygons ∙ By: TantekÇelik<br />
- 19. Line Symmetry<br />Q: Does anyone know what line symmetry is?<br />D. Line symmetry is when one half of an image is the mirror image of the other half <br />Sometimes shapes/figures can have more than one line of symmetry.<br />This is an example of a pentagon <br />having line symmetry<br />See if you can figure out anymore lines on symmetry between either the pentagon or the hexagon<br />Review: Line Symmetry∙ By: homeschoolmath.net<br />
- 20. Rotational Symmetry<br />Q: Does anyone know what rotational symmetry is?<br />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)<br />Review: Rotational Symmetry∙ By: Webquest<br />
- 21. Geometry in the Every Day<br />Geometric shapes can be found everywhere. Here are some examples of geometric shapes in the nature<br />Lines symmetry can also be found everywhere. Here are some examples of geometric shapes in the nature<br />
- 22. Activities with Geometric Shapes<br />Check out EnchantedLearning.com for teaching geometric shapes in the classroom. They have worksheets, crafts and much more!<br />
