The app for calculations of angles, sides, perimeter, area, volume in triangle, rectangle, circle, sphere and rectangular cuboid is a versatile tool designed to help you perform various geometric calculations quickly and easily. Depending on the selected shape, the calculator allows you to perform various calculations. For triangles, you can calculate angles, sides, perimeter and area. For rectangles, you can calculate sides, perimeter and area. For circles, you can calculate the radius, diameter, circumference and area, or volume and surface area of a sphere. For rectangular cuboid, you can calculate sides, surface area, base area, and volume. The app has a simple and intuitive interface that makes it easy to input your values and get your results quickly. After entering any value, the figure will immediately be recalculated based on the last data entered. Interactive animated visualisation provides additional representation of the shape and the changes made to it. The units of angles, length, area and volume, as well as the number of decimal places can be adjusted as required. The geometry calculator is a powerful and convenient tool that can help you perform a wide range of geometric calculations with ease.
