Four Sided Pyramid
Simple steps to make a four sided pyramid
Draw a triangle in the front plane. I want to make a pyramid with a square base and each side of the pyramid having same dimensions. Hence I'm drawing an equilateral triangle.
Extrude the triangle having the same dimensions of extrusion as the sides.
Draw another triangle on the right plane with the vertices adjoining the sides of the triangle.
Extrude cut the part out side the triangle to form a pyramid.
You get a pyramid with equal sides and a square base.
