1.	What will be the sum of internal angles of a septagon?(a) 650(b) 700(c) 450(d) 900The question was posed to me in an online quiz.The origin of the question is Properties of Polygons-1 topic in portion Quadrilaterals of Mathematics – Class 8
Answer» The CORRECT choice is (d) 900 To ELABORATE: The sum of the interior ANGLES of a polygon can be calculated using the formula = (number of sides – 2) × 180 Here, number of sides is 7. So, the sum of interior angles of a septagon = (7 – 2) × 180 = 5 × 180 = 900
