You may get three to five questions from Geometry and Solid Geometry in the GMAT quant section - in both variants viz., problem solving and data sufficiency. The concepts tested include lines, angles, triangles, quadrilaterals, circles, coordinate geometry, solid geometry, finding the area, perimeter of two dimensional geometric shapes and surface area, volume, longest diagnal of solids including cones, cylinders, cube, rectangular cube, sphere, and hemisphere.

Sample GMAT practice questions from Geometry is given below. Attempt these questions and check whether you have got the correct answer. If you could not get the answer, go to the explanatory answer or the video explanations (wherever provided) to learn how to solve the question.
