In the diagram below, which edges of the prism are parallel to ad ? (select all that apply.)

dh
bc
ef
fg

Given is the shape of a rectangular prism. All the parallel edges are diagonally opposite to each other, it means that parallel edges directly face opposite to each other and they do not have any common vertex. So we have two sets of parallel edges that are {AB, CD, EF, and GH} and {AD, BC, EH, and FG}.

It says to select all edges from the given options that are parallel to AD.

Given options are :- 1. DH, 2. BC, 3. EF, 4. FG.

We have AD ║ BC ║ EH ║ FG.

Hence, only BC and FG are the final answers.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

my answer is$ 12

step-by-step explanation:

because 15 -2=12
