State if the two triangles are congruent. If they are, prove by using a two column proof!!!

you can prove that they are congruent if their angles are the same.

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

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 "
