Note: After about 6 **sides** mathematicians usually refer to these **polygons** **as** n-gons, so a 23 sided **polygon** would be called a 23-gon. The sum of the **measures** **of** **the** **angles** **of** **a** convex **polygon** with n **sides** is (n - 2)180. If you extend each side of a polygon to form one exterior angle at each vertex, you get a set of exterior angles. This conjecture tells us that the sum of a set of exterior angles is 360 degrees. This result, all by itself is not so exciting. The resulting corollaries about regular polygons are much more interesting. In a certain **regular** **polygon**, **the** **measure** **of** **each** interior **angle** is 12 times the **measure** **of** **each** **exterior** **angle**. **Find** **the** number of **sides** in this **regular** **polygon**. These two **measurements** enable the survey team to calculate position B as in an open traverse. The surveyors next **measure** the interior **angles** CAB, ABC, and BCA at point A, B, and C. Knowing the interior **angles** and the baseline length, the trigonometric "law of sines" can then be used to calculate the lengths of any other **side**. VIDEO ANSWER: There's always 360° for **exterior angle**, so if it's a **regular polygon**, you just divide by the number of **sides** to **find** out how much **each** one is. So if N is eight a quadrilateral, then it would be 360 di. x° + 2x° + 89° + 67° = 360° **Polygon Exterior Angles** Theorem 3x + 156 = 360 Combine like terms. x = 68 Solve for x. The value of x is 68.

Q. **Find** **the measure of each exterior angle** **of a regular** **polygon** of (i) 9 **sides** (ii) **15** **sides**. add up the **exterior angles** between the extension of one **side** and the next **side**. They must add up to 360 because they go all the way around. Then the interior **angle** is the supplement. For example for a **regular** pentagon **exterior** between **side** extension and **side** = 360/5 = 72 so **each** interior **angle** is 180 - 72 = 108. If you cut a pizza into four big slices and then cut **each** of those slices in half, you get eight pieces, **each** of which makes a 45° **angle**. If you cut the original pizza into 12 slices, **each** slice makes a 30° **angle**. So 1/12 of a pizza is 30°, 1/8 is 45°, 1/4 is 90°, and so on.

Question 2 (i) **Find** **the measure** **of each** **exterior** **angle** **of a regular** **polygon** of: (i) 9 **sides**.. The interior angles of a regular polygon are each 120°. Calculate the number of sides. The interior angles are 120°, so the exterior angles are 180° - 120° = 60°. The exterior angles add up to 360°, so if we divide 360° by 60° we find there are 6 exterior angles. 2 How many sides does a polygon have if the sum of the interior angles is 2340?. The formula for the circumference of a circle is 2 x π x radius, but the diameter of the circle is d = 2 x r, so another way to write it is 2 x π x (diameter / 2).

Solution: Question 9. The ratio between the interior **angle** and the **exterior angle of a regular polygon** is 2 : 1. **Find**. add up the **exterior angles** between the extension of one **side** and the next **side**. They must add up to 360 because they go all the way around. Then the interior **angle** is the supplement. For example for a **regular** pentagon **exterior** between **side** extension and **side** = 360/5 = 72 so **each** interior **angle** is 180 - 72 = 108. As you walk around the room, students should be heard discussing how a straight **angle** **measures** 180 degrees and the three **angles** of a triangle form a straight **angle** . As a class, create a formal statement about the sum of the **angles** of a triangle , while you write it on the board:.. An octagon has eight **sides**, so the sum of the **angles** of the octagon is 180(8 – 2) = 180(6) = 1080 degrees. Because the octagon is **regular**, all of its **sides** and **angles** are congruent. Thus, **the measure of each angle** is equal to the sum of its **angles** divided by 8. Therefore, **each angle** in the **polygon** has a **measure** of 1080/8 = 135 degrees. This. **Regular** **polygons** with equal **sides** and **angles** **Polygons** are two dimensional geometric objects composed of points and line segments connected together to close and form a single shape and **regular** **polygon** have all equal **angles** and all equal **side** lengths. **The** **measure** **of** **each** interior **angle** is (n-2)(180/n) and the **measure** **of** **each** **exterior** **angle** is 360/n. We should double check that a pentagon IS the correct **polygon**. 7. 900°. Octagon. 8. 1080°. The **measure** of **each** internal **angle** in a **regular polygon** is **found** by dividing the total sum of the **angles** by the number of **sides** of the **polygon**. For example, we. Answer (1 of 4): The **exterior angle** is the supplement of the interior **angle**. We know the sum of the interior **angles** is (N-2)*180 degrees for an N-**sided polygon**.
