Which statements are true about the lines of symmetry of a regular pentagon? check all that apply.

a
every line bisects a vertex angle.

b
every line connects the midpoints of 2 sides

c
every line is perpendicular to a side.

d
every line bisects a side

e
every line connects two vertices.

The correct answers are:

a ) Every line bisects a vertex angle.

c) Every line is perpendicular to a side.

d ) Every line bisects a side .

Explanation:

The lines of symmetry are the lines through which we can "fold" the figure in half. In order to for it to be exactly in half in a pentagon, each of these lines will need to go from a vertex to the opposite side.

Since it divides the figure into halves, this means it bisects the vertex angle as well as the opposite side.

In order for it to bisect both of these, the line must be perpendicular to the opposite side.

Answer;

-Every line bisects a vertex angle.

-Every line bisects a side.

-Every line is perpendicular to a side.

Explanation;

-A regular polygon is a polygon whose sides are equal in length, and thus the interior angles are also equal in size. For example, a regular quadrilateral is a shape that has four equal sides, with all the interior angles equal.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
