Often the answer is always the same for every problem in the group. This makes the computations easy for the teacher, or student, to check, and emphasizes that it is the 'workings' that count. The Babylonians did use geometrical constructions in their problems, although, as mentioned before, the purpose of a problem is the computation of a number. For geometric objects, this typically means lengths of sides or diagonals, or determination of area or volume. The Old Babylonians had no measurement of angle, which to us is such a basic part of geometry.
Angles are a later development.
Some tablets do have figures drawn on them, and there are surviving problems to do with all the standard shapes such as squares, rectangles, triangles, trapezoids, circles, and so on. Some of the problems become very sophisticated. Solid geometry is dominated by bricks and ramps, but cylinders and truncated cones and pyramids do make an appearance. There are some examples of virtuoso work, and it is not clear to us how much mathematical training the average scribe had. We do not know if every student would have been expected to understand all the mathematics for which we have evidence, or if there was some degree of specialization.
