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. The bigger the fraction of the pizza, the bigger the angle.

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:.. 22/6/2018 · Prakhar2908. Heya ,find the measure of each exterior angle of a regular polygon of. I) 9 sides. ii) 15 sides. The answer of this question is:-. (1) we have to just divide 360° by no. of sides. Here, 360/9. =40°.. Let number of sides be = n. Measure of each interior angle = 165 ° Measure of each exterior angle = 180° - 165 ° = 15° [Since, an interior and an exterior angle forms a linear pair] Number of sides = Sum of exterior angles / Each exterior angle = 360° / 15 = 24 Hence, the regular polygon has 24 sides .. So, our new formula for finding the measure of an angle in a regular polygon is consistent with the rules for angles of triangles that we have known from past lessons. If each exterior angle measures 15°, how many sides does this polygon have?. The measure of each exterior angle of a polygon = 360/n. So, 360/n = 50° n = 7.2 No, we cannot have a regular polygon with each exterior angle 50°. Ques. Find the measure of each interior angle of a regular polygon having (3 marks) 10 sides; 15 sides ; Ans. Each exterior angle = 360/n (n = no. of sides of polygon) Exterior angle = 360/ 10 = 36°. Find an unknown angle in a triangle #7–12, 17–20. Find angles formed by parallel lines and a transversal #13–16, 35–44. Find exterior angles of a triangle #21–24. Find angles in isosceles, equilateral, and right triangles #25–34. State reasons for.
