Geometry Pad is a dynamic geometry application for iPad.  With the Geometry Pad you can create fundamental geometric shapes, explore and change their properties and calculate metrics. The shapes are displayed on a scrollable and zoomable workbook with a rectangular coordinate system. The following tools are built into the application:  - Move and scale. Scroll the workbook by your finger. Pinch and zoom the content of your workbook. Move and modify shapes.  - Point. Plot a point on the workbook. Customize point name and color.  - Line. Create a line. Customize line style, color and start/end points. Calculate line length (distance between points).  - Midpoint for lines. Show/hide midpoint for lines and polygon sides. Snap to midpoints.  - Parallel, perpendicular and tangent lines. The lines can be created as easily as regular lines. Just create and move the line until it automatically snaps to parallel, perpendicular or tangent.  - Angle. Create an angle with up to 1 degree precision. Customize angle line style and color.  - Triangle. Create a triangle of one of the predefined types: regular, right triangle, isosceles, equilateral. Customize sides style and color. Calculate triangle perimeter and area. Calculate inner angles of the triangle and length of its sides.  - Triangle lines. Create altitude, bisector and median lines in a triangle. Calculate length of triangle lines. Customize lines style and color.  - Quadrilateral. Create a quadrilateral of one of the predefined types: regular, square, rectangle, parallelogram, rhombus. Customize sides style and color. Calculate quadrilateral perimeter and area. Calculate inner angles of the quadrilateral and length of its sides.  - Circle. Create a circle. Calculate circle perimeter and area. Easily create circles inscribed into a triangle by placing circle's center close enough to the incenter of a triangle.  - Circle radius and chord. Create radius and chord lines for a circle. Customize lines style and c

This lesson involves students in collecting data, organizing data into a line plot, discussing statistics, calculating mean, median and mode and consumer awareness.
