PPT-Surface Area of Pyramids

ADDITION TO DIAGRAM NEW VOCAB The slant height of a regular pyramid is the distance from the vertex to the midpoint of an edge of the base The lateral faces of a regular pyramid can be arranged to cover half of a rectangle with a height equal to the slant height of the pyramid The width of the rectangle is equal to the base perimeter of the pyramid.
