A Straight-Sided Pyramid features which characteristic?

• A. Sides are curved and converge to a rounded apex
• B. Sides are straight and converge to a single apex
• C. Sides are stepped in a terraced fashion
• D. Base is circular

Answer: (B)

In a straight-sided pyramid, the side faces are flat planes that come together at a single apex. Each face is a straight-sided triangle that slopes from the base up to one top point, forming a sharp vertex above the base. The base is a polygon, and straight edges run from the apex to the base corners. If the sides were curved, you’d have a curved-faced form rather than a straight-sided pyramid. If the sides were terraced, the figure would be a stepped pyramid. If the base were circular, you’d be looking at a cone, not a pyramid.
