All of the following are diagonals of the solid except

as
bt
ac
cq

AC

Step-by-step explanation:

We know that a 'diagonal' is the line segment that joins the two vertices of a figure, where those vertices lie on the opposite edges.

i.e. any line segment that slopes in the figure is called a diagonal.

Now, as we can see from the given figure that line segment AS, BT and CQ are sloping inside the figure and are joining the opposite vertices.

Hence, these three are diagonals.

Whereas, the line segment AC does not slope and also both the vertices A and C lie on the same edge.

Hence, AC is not a diagonal.

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
