Answer:

(a) It is not a polygon as it is not a closed figure.

(b) Yes, it is a polygon made of 6 sides.

(c) No, it is not made of line segments.

(d) No, it is not made of only line segments.

Question 2:

Name each polygon.

Question 5:

A diagonal is a line segment that joins any two vertices of the polygon and is not a side of the polygon. Draw a rough sketch of a pentagon and draw its diagonals.

Answer:

It can be observed here that AC, AD, BD, BE, CE are the diagonals.
