Focusing on the question, "By how much does light refract when it crosses a boundary?" this physics tutorial will allow students the opportunity to explore these concepts of refraction.

This multimedia Learn Alberta math resource looks at angles of a triangle in the context of building bikes and choosing bike sizes. The accompanying interactive component lets students explore build different sized triangles while...

In this activity, students will measure angles and investigate the relationships between interior and exterior angles of a triangle. They understand the definition of interior angles, exterior angles, adjacent angles, supplementary...

In this activity, students investigate the sum of the measures of the interior angles of a triangle. They will explore interior angles, and their relationship with the exterior angles of a triangle.

Explain that the sum of exterior angles of polygons equal 360 degrees.

This site gives a definition of angle of rotation and provides some examples. There is also an interactive activity in which a JavaSketchPad page is provided for you to explore rotations. In addition, be sure to follow the links to...

[Free Registration/Login Required] In the scenario shown here, the laser cannot shine through the black barrier but can hit all three targets by reflecting off of the floor. Use the red dot to change the angle of the laser generator and...

A great resource where you can learn how to calculate the measures of the interior and exterior angles of any regular polygon with these tutorials. There are several practice pages for someone to try. The teacher resource page includes...

Learn what an interior angle of a polygon is and how you can calculate their value in triangles, quadrilaterals, and pentagons. Includes a chart that overviews the "general rule" for determining the sum of internal angles in any polygon...

Determine the sum of the interior angles of polygons.

This tutorial with video and slideshow components investigate the characteristics of polygons as well as how to calculate the interior and exterior angles of any polygon. It offers two PowerPoint presentations and two videos that feature...

Given numerical and/or geometric patterns that represent geometric properties of angle relationships in polygons, the student will investigate patterns to make conjectures about interior and exterior angles of polygons.

Explore forces, energy, and work as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet. Graphs show forces, energy and work.

Which object takes more energy to push up a ramp: a file cabinet, a refrigerator, a piano, or a sleepy dog? Find out in this ramp simulation when you change the angle of the incline, change the objects, or change the friction on the ramp.

A geometry proof involving exterior angles of a triangle.

On this site a viewer can learn about the different types of triangles, and categorized by either angles or sides. Tutorials are also included for interior and exterior angles of triangles. A teacher resource page includes a lesson plan...
