You can change the lengths of the legs (dragging), the length of the hypotenuse with two fingers and zoom (pinch zoom) and rotate the figure (dragging). There are 3 ways to view the Pythagorean theorem, including showing the unit surfaces, two equivalent squares containing the same surface and the square for each leg in the square of the hypotenuse. You can change the precision of the lengths. ***FEATURED TOOL Tool: Parachute Drag http://mathforum.org/mathtools/tool/23644/ Maryland Virtual High School Explore the effects of mass, displacement, and drag on the functioning of a parachute in this simulation. ***FEATURED TOOL Tool: Coin Box http://mathforum.org/mathtools/tool/134190/ NCTM: Illuminations Learn how to count, collect, exchange, and make change for coins. The coin tiles help you count as you learn the value of each coin. How many of the games can you master? ***FEATURED TOOL Tool: Data Games: Lunar Lander http://mathforum.org/mathtools/tool/188497/ KCP Technologies, U Mass-Amherst Students develop their skills with polynomial and rational expressions to create formulas that evaluate lunar landings.
