Pyramid There are a lot of interesting parts to a pyramid We will focus on pyramids that have regular polygons. Published by Giles Curtis Modified over 2 years ago. The base of a regular pyramid is a regular polygon, and the lateral faces are congruent isosceles triangles. The slant height of a regular pyramid is the distance from the vertex to the midpoint of an edge of the base. Find the surface area of the composite figure. Exploring Effects of Changing Dimensions The base edge length and slant height of the regular hexagonal pyramid are both divided by 5. The surface area is multiplied by.
