Geometry AR is a tool for viewing and learning about geometric figures using Augmented Reality technology (AR). With Geometry AR kids can view planar and solid figures by actually walking around the figure in order to view all sides. Students use the slider or arrow buttons to move through a list of over 25 figures. As figures are selected they instantly appear in the AR view and can be viewed by moving around the virtual object. Screens of information about the geometric figure are displayed when the notebook icon is tapped. If the sound has been activated by tapping the speaker icon, the text will be read aloud. Geometry AR is perfect for mathematics classrooms where geometry concepts are being introduced. Augmented Reality adds a level of interest and excitement that will stimulate young minds to further exploration. Be sure that your iPad allows access to the camera function by choosing Settings -> General -> Restrictions -> Off. Figures Included: point ray line segment line angle arc parallel lines perpendicular lines intersecting lines circle triangle right triangle acute triangle obtuse triangle rectangle square parallelogram trapezoid regular prism rectangular solid circular cylinder pyramid circular cone sphere skew lines polyhedron torus ellipse parabola hyperbola
