Answer:Activity 1
1. Hexagon - The sum of the interior angles of a hexagon is 720°
2. Octagon - The sum of the measures of the interior angles of an octagon =(8−2)180° . The sum of the measures of the interior angles of an octagon is 1080° .
3. Decagon - The sum of the measures of the interior angles of a decagon (10 sided polygon) is 1,440. We found this by using the formula (n-2)(180). Thus, to find the measure of each interior angle we simply divide the sum by the number of total sides in the polygon. 1,440/10 = 144.
4. 15-gon - The sum of the interior angles of a polygon =(n−2)×180
o
.
Where n is the number of sides of the polygon.
Here, n=15
∴ The sum of the interior angles of a polygon =(15−2)×180
o
.
=13×180

=156
5. the sum of the interior angles of an 18 sided polygon is 2880
Activity 2
1.360° - There are six angles, so 720 ÷ 6 = 120°. Each interior angle of a regular hexagon has a measure of 120°. Because the sum of these angles will always be 360°, then each exterior angle would be 60° (360° ÷ 6 = 60°).
2. A convex regular nonagon has 9 congruent exterior angles. 9n = 360 n = measure of each exterior angle n = 40 Divide each side by 9. The measure of each exterior angle is 40.
3. The sum of the exterior angles in any convex polygon, including a regular 15-gon, is 360∘.
4.The measure of each exterior angle of a regular polygon of 18 sides is 20 degrees.
5. Therefore 20 -gon has 20 exterior angles whose sum is 360∘
