(b) Two adjacent angles cannot be supplementary (c) An acute angle cannot be adjacent to an obtuse angles. Can an acute angle be adjacent to an obtuse angle? a. but an acute angle is always less than 90 degrees, so two acute angles cannot add up to equal 180 degrees/be supplementary. These ARE Adjacent Angles. Can two adjacent angles be complementary. (iv) Two adjacent angles always form a linear pair. Supplementary angles mean that the sum of the 2 adjacent angles is 180 deg. They cannot be supplementary. 1. we have ∠x = ∠55° (Vertically opposite angles) ∠x + ∠y = 180° (Adjacent angles) Yes, two acute angles can be complementary to each other. Give reasons.

(False) Correct : As the sum of two obtuse angles is greater than 180°. We know that angles measuring greater than 0° and less than 90° are called acute angles in geometry. Complementary angles always have positive measures. Yes, an acute angle can be adjacent to an obtuse angle. Explain with the help of diagram. Students can solve NCERT Class 7 Maths Lines and Angles MCQs Pdf with Answers to know their preparation […] Adjacent angles can be supplementary in two different ways: on a line and in quadrilaterals. Which means we will be creating a fairly pointy shoe! The nonadjacent rays of two adjacent, complementary angles are perpendicular. (ii) Since, obtuse angle > 90° ∴ Obtuse angle + obtuse angle > 90° + 90° > 180° Can two adjacent angles be supplementary. 5.2.4 Linear Pair A linear pair is a pair of adjacent angles whose non-common sides are opposite rays. ∠1 and ∠2 are vertical angles. For e.g. non adjacent angles, Sum of the two two adjacent angles is 130 °. Pope. Prove with diagram. Can two adjacent angles be complementary? Can two obtuse angles be adjacent angles? For example, Two acute angles can be vertical,adjacent,complementary. Adjacent angles can be supplementary, but they don't have to be. the term adjacent means next to each other. An Angle that is greater than 90° but less than 180° is known as an Obtuse Angle. Given : T he second angle is 4 more than six times of the first angle. Obtuse Angle & Its Properties. In that case it would be a reflex angle, not an obtuse angle. In this diagram you can see one of the angles in the linear pair ( two angles sharing a common vertex, common arm and are adjacent to each other ) is 45 degrees ( which is an acute angle ) and the other angle is 135 degrees ( the angle on the left side ) and it is an obtuse angle.
