Question

the given three - dimensional solid is
one of the bases is
edge jm intersects edge lm at point

Explanation:

Step1: Identify the 3 - D solid

It appears to be a triangular prism as it has two triangular bases and three rectangular lateral faces.

Step2: Determine the base

The bases are the triangular faces. For example, triangle HJK can be considered a base.

Step3: Find the intersection point

The edge $\overline{JM}$ and edge $\overline{LM}$ intersect at point $M$ as it is the common endpoint of both edges.

Answer:

The given three - dimensional solid is a triangular prism.
One of the bases is $\triangle HJK$ (or $\triangle MIL$).
Edge $\overline{JM}$ intersects edge $\overline{LM}$ at point $M$.
