Lines and angles class 9 axioms
NettetAngle Sum Property and Axioms - Lines and Angles, Class 9, Mathematics Download Ex. In figure, are complementary angles. Find the value of x and hence find Sol. In figure, We have, ∠AOC + ∠BOC = 90 ⇒ (x+ 10) + (2x + 5) = 90 ⇒ 3x + 15 = 90 ⇒ 3x = 90 – 15 = 75 ⇒ x = 25 Now, ∠AOC = (25 + 10) = 35 and ∠BOC = {2 25 + 5} = 55 Ex.

NettetAxiom 2. If the sum of two adjacent angles is 180º, then the non-common arms of the angles form a line. It is called Linear Pair Axiom. Theorem 1. If two lines intersect each other, then the vertically opposite angles are equal. Solution: Given: Two lines AB and CD intersect each other at O. To Prove: Ray OA stands on line CD.
NettetWhen 2 lines join each other at 90°, then the angle formed is called a Right Angle. If the value of the angle is more than 90° but less than 180°, then the angle is called Obtuse Angle. A Reflex Angle is the larger angle when the angle is more than 180° but less than 360°.
