**Ex 5.8 Class 6 Maths Question 1.**

Examine whether the following are polygons. If any
one among them is not, say why?**Solution:**

We know that a polygon is a closed figure bounded by
line segments.**
**(a) The given figure is not closed. Therefore, it is not a polygon.

(b) The given figure is a polygon because it closed and bounded by 6 line segments.

(c) The given figure is not a polygon because it is not enclosed by line segments.

(d) The given figure is not a polygon because it is enclosed by an arc and two line segments.

**Ex 5.8 Class 6 Maths Question 2.**

Name the polygon.Make two more examples of each of these.

**Solution:
**(a) This is a quadrilateral. Examples:

(b) This is a triangle. Examples:

(c) This is a pentagon. Examples:

(d) This is an octagon. Examples:

**Ex 5.8 Class 6 Maths Question 3.**

Draw a rough sketch of a regular hexagon. Connecting
any three of its vertices, draw a triangle. Identify the type of the triangle
you have drawn.**Solution:
**ABCDEF is a rough sketch of a regular hexagon. If we
join any three vertices like D, A and B, we get a scalene triangle ABD.

But if we join the alternate vertices, we get an equilateral triangle ACE.

**Ex 5.8 Class 6 Maths Question 4.**

Draw a rough sketch of a regular octagon. (Using
squared paper if you wish). Draw a rectangle by joining exactly four of the
vertices of the octagon.**Solution:
**ABCDEFGH is a rough sketch of a regular octagon. CDGH
is a rectangle formed by joining the four vertices of the given octagon.

**Ex
5.8 Class 6 Maths 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.**Solution:
**ABCDE is the rough sketch of a pentagon. By joining
any two vertices, we get the following diagonals.

AC, AD, BD, BE and CE
