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 color. Calculate the length of the lines.
 Polygons and regular
polygons.
 Arcs and circular sectors.
 Ellipses.
 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.
 Transformation tools: rotation,
reflection, enlargement and translation.
 Manual input of coordinates, lengths and angles. Use manual input to
precisely locate points, setup custom length for a line or a polygon side, and change angle value.
 Builtin
calculator: basic arithmetic functions, square root, sin, cos, tan.
Manage multiple workbooks at the same time
using Save and Load features. In addition, you can share documents through email or Dropbox.
Some of the tasks
you can solve with Geometry Pad:
 Create geometric shapes and measure all its possible metrics like length,
angle, area, perimeter, intersections, distance between points, angles between lines.
 Move/resize geometric
shapes and watch how its metrics are changing in real time.
 Demonstrate circle theorems by creating and changing
inscribed and center angles.
 Demonstrate theorems about incircles and excircles locations.
 Create and
annotate complex geometric figures. Share them through export to image and email features.
