The application of geometric shapes enables you to know the properties and laws of a group of designing engineering shapes such as square, triangle, rectangle, circle and parallelogram, and another group of solids such as cube, ball, cylinder and parallel rectangles, by entering the values ​​of length, width, height, and base Or diameter, you get the circumference, area, and size. It also benefits pupils to learn the regular geometrical shapes, such as the cube, the ball, the cylinder, and parallel rectangles. The application is free, easy to use, light and supports the most prevalent languages ​​according to the language of your phone. It also allocates a page for each engineering figure showing the the geometric shapes names, the laws of the shape and the required inputs and the result of the calculation and a small picture that shows the engineering shape. The application is useful for first, second and primary graders and is useful for a number of students in the field of spaces. The application includes engineering shapes 3d and 12 sides
