# The measure of each interior angle of a regular polygon with 8 sides is :

- 120
^{o} - 100
^{o} - 45
^{o} - 135
^{o}

**135 degree **

**Explanation:-**

**Formula-**

**The measure of each interior angle of a regular polygon = (n – 2) 180/n**

**Where, n = the number of sides in the polygon.**

Here, n = 8

Then, the each interior angle of a regular polygon = (8 – 2) 180/8

= 6 x 180/8

= 135º

Hence, the correct answer is option (4) 135º.
