In the diagram, the ratios of two pairs of corresponding sides are equal. to prove that △lmn ~ △xyz by the sas similarity theorem, it also needs to be shown that a.∠n ≅ ∠z b.∠n ≅ ∠x c.∠l ≅ ∠z d.∠l ≅ ∠y

1 is b and 2 is d

step-by-step explanation:

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 "
