Geometry Questions and Answers for Your Practice

Geometry is an important topic in mathematics, where questions are related to the shape, angle, dimension, and shape of various things that come under this topic. Geometry is derived from ancient Greek words - 'geo' meaning 'earth' and 'metron' meaning 'measure'. In Euclidean geometry, there are two-dimensional shapes and three-dimensional shapes. With the help of this topic, we can calculate the area, perimeter, and volume of cubes, cuboids, cones, triangles, squares, rectangles, circles, etc.

Every year questions are asked about this topic. This topic is difficult as compared to other subjects, but if you practice these questions continuously, then you can definitely master this subject.
