GOOD NIGHT ❤️ ምናልባት ነገ አዲስ ነገር ይኖራል ጠብቁን ❤️👏

Q1, A, 144 B,150 Q2, 150 Correct answer 👏👏👏 Abdi Elroi ♾ በትክክል መልሰዋል 👏👏👏👏👏🫶

Q1, find the measure of an interior angle of a regular polygon with: A, 10 sides B, 12 sides Q2, Find the number of sides of a regular polygon, if the measure of each of its interior angle is 150⁰? You are 10 minutes ......👏✍✍

ወደ Work out እንሂድ ግን ፍላጎት ያላችሁ አትመስሉም 😝🧐

Note Book 👉 For any regular n-sided polygon 🛠 Measure of each interior angle = (n-2)180⁰/n 🛠 measure of each centeral angle = 360⁰/n 🛠 measure of each exterior angle = 360⁰/n. Don't forget to react our post❤️👏👏

Reaction አይታየኝም 😳😒

NB 👉 The measure of each interior angle of a regular n - sided polygon is n-2*180⁰/n. 👉 A polygon is said to be inscribed in a circle if all of it's vertices lie on the circle. 👉 the measure of an interior angle of an n-sided regular polygon is S/n, where S=(n-2)*180⁰.
