# 7th Grade Geometry and Measurement Resources

This demonstrates how, by removing squares from the corners of a rectangle, we create the net for an open-topped rectangular prism. For a given set of dimensions, experiment to see what size squares will maximize the volume of the prism.

Starting with a pre-image, draws the image for scale factor of your choosing. Click on the sides to show/hide their lengths.

Simple program that shows the supplement and complement of the angle. You can choose to show/hide angle measures.

What patterns can we notice about possible combinations of side lengths? In other words, can we discover the Triangle Inequality Theorem?
