Tessellate! (Activity)
Create a tessellation by deforming a triangle, rectangle or hexagon to form a polygon that tiles the plane. Corners of the polygons may be dragged, and corresponding edges of the polygons may be dragged. Parameters: Colors, starting polygon.
Examines plane symmetry.
Looks at how Pascal's Triangle can be used to generate Sierpinski triangle-like results.
This worksheet is for use with the Translations, Reflections, and Rotations lesson plan (http://shodor.org/interactivate/lessons/TranslationsReflectionsRotations/).
Explore the mathematical nature of art and tilings and looks at the role of math in nature and our culture.
This worksheet is for use with the Sierpinski's Triangle activity (http://www.shodor.org/interactivate/activities/SierpinskiTriangle/).
Explores lines, planes, angles, and polygons in tessellations.
Transmographer (Activity)
Explore the world of translations, reflections, and rotations in the Cartesian coordinate system by transforming squares, triangles and parallelograms. Parameters: Shape, x or y translation, x or y reflection, angle of rotation.
Slant Height (Discussion)
Introduces the concept of the slant height of a triangle and how to find its measure using the Pythagorean theorem.
Students learn how the Pythagorean Theorem works and how to apply it.
