[b]Use the figure below to answer the following questions.[/b]
Use sliders a and b to change the side lengths of the kite. Use the sliders to rotate all four triangles. [b]Note: To use each slider, drag the point along the line.[/b] [list=1] [*][b]Rotate all four triangles:[/b]What shape does the kite and four triangles form? [*]What is the area of this shape, in terms of d1 and d2? [b](Note: d1 and d2 represent the diagonals of the kite.)[/b] [*]Write a formula for the area of kite ABCD in terms of d1 and d2. [b](Hint: Area of Kite = Area of Rectangle - Area of (Blue) Triangles )[/b] [/list]
