Atriangle with vertices at a(0, 0), b(0, 4), and c(6, 0) is dilated to yield a triangle with vertices at a′(0, 0), b′(0, 10), and c′(15, 0). the origin is the center of dilation. what is the scale factor of the dilation?

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
