|Tool: Area of a Rhombus - Math Open Reference||
|Go to:||http://www.mathopenref.com/rhombusarea.html (opens a new window)|
A web page and interactive applet showing the ways to calculate the area of a rhombus.The user can drag the vertices of the rhombus and the other points change automatically to ensure it remains a rhombus. A grid inside the shape allows students to estimate the area visually, then check against the actual computed area.
The text on the page gives three different ways to calculate the area with a formula for each. The applet uses one of the methods to compute the area in real time, so it changes as the rhombus is reshaped with the mouse.
Applet can be enlarged to full screen size for use with a classroom projector. After use in the classroom, student can access it again from any web browser at home or in the library with no login required.
