Will give a brainlest and 20pts which figures can be precisely defined by using only undefined terms? check all that apply. angle arc circle line segment parallel lines

We can define circle, line segment and parallel lines with the help of undefined terms.

Step-by-step explanation:

The undefined terms in geometry are line, plane and points.

So, we can define line segment, circles and parallel lines with the help of undefined terms.

A line segment is a part of a line that contains two distinct end points.

A circle is defined as a figure with a set of points that are all equidistant from a fixed point called the center.

Parallel lines are lines in a plane that never meet or intersect at any point.

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
