Common Core State Standard 6.G.A.1 - Area of Right Triangles

This applet supports the Common Core State Standards for Mathematics Content. The Standard represented is 6.G.A.1, which states: "Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems" (Source: http://www.corestandards.org/Math )[br][br]In this applet, you can adjust the height and base of the right triangle and see what happens to the triangle's area.
