Tripp Martin · Answer 1

Step-by-step explanation:

remeber this rule

sum = (n-2) * 180°

n is no of side

take that away from 2

multiply 180

e. g triangle

3 sides

take away 2

3-2 is 1.

multiply by 180

1*180 is 180°

Cheyenne Ho · Answer 2

Answer: Memorise the rule that the sum of the interior angles of a polygon = (n-2) * 180°, and that each interior angle of a regular polygon can be calculated by the rule: (n-2) * 180° / n, where 'n' refers to the number of sides.
