Answer 2

Answer:

The formula for finding the sum of interior angle of polygon is    

A pentagon has 5 sides.

So    

The total angles of a pentagon shall be

Now to find the measure of each interior angle we divide the total angles by 5.

We get

Each interior angle =    

We shall first draw a segment of 3cm

 

Now we shall draw angles of 108° on both ends at A & B.

And cut arcs at 3 cm each from A & B.

 

Now once again draw angles of 108° at E & C

 

Now draw a similar pentagon in such a way that DS = 8cm And join the respective vertices.

 The obtained figure is a pentagonal prism
