geometry pad is a dynamic geometry application for ipad and android tablets. geometry pad is your personal assistant in teaching and learning geometry through practice.
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. create, modify and measure 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. use snapping to create center and inscribed angles and to investigate circle theorems. 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. circle radius and chord. create radius and chord lines for a circle. customize lines style and color. calculate the length of the lines. text annotations. create floating and pinned single and multiple lines text annotations. customize text/background color and transparency. measurements tool. measure shape properties in single touch. measure intersection points (line & line, line & circle). use multitouch to measure distance between points and angle between lines.
