Which figures can be precisely defined by using only undefined terms? check all that apply.

angle
arc
circle
line segment
parallel lines

Angle, circle, line segment, parallel lines can be precisely defined by using only undefined terms.

Step-by-step explanation:

In geometry , simple definitions of the given terms are as follows:

Line segment - A line with two end points.

Parallel lines - Two lines which never intersect.

Circle -A circle is the set of all points which are equidistant from a given point known as center of circle.

Arc - A curved line that is part of the circumference of a circle.

Angle - A shape, formed by two lines diverging from a common point .

Here all can be precisely defined by using only undefined terms except an arc.

Therefore, an angle, circle, line segment, parallel lines can be precisely defined by using only undefined terms.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
