Question

Are the statements Always, Sometimes or Never. Please explain why. Thanks.
1. An equilateral polygon is regular.
2. The greater the number of sides of a regular polygon, the smaller the measure of any of its exterior angle.
3. The sum of the measures of the interior angles of a polygon is a multiple of 360.

Answer 1

1. "equilateral" means equal sides, but says nothing about its angles. How is regular defined ?

2. give yourself an example,
e.g. consider a hexagon and an octogon, and see what happens

3. but the formula says 180(n-2) as the sum, so ....
e.g. take a heptagon, n = 7, so is 180(7) divisible by 360 ?
