Performance & security by Cloudflare, Please complete the security check to access. (a) Two acute angles can be complementary to each other (b) Two obtuse angles can be complementary to each other (c) Two right angles can be complementary to each other (d) One obtuse angle and one acute angle can be complementary to each other. 6. 4. And if two acute angles are added then their sum will be less than 180 0 which contradicts the definition of the supplementary angle. They just need to add up to 90 degrees. A linear pair forms a straight angle of 180 degrees, so you have two angles whose sum is given as 180, which means they are supplementary. ∠ θ is an acute angle while ∠ β is an obtuse angle. If you add two acute angles in which each angle is large as possible, its sum will be less than 180°. (v) Pair of vertically opposite angles are always supplementary. When the sum of the measures of two angles is 90°, the angles are called complementary angles. SOLUTION As each of the angle is $$<90^0$$.So, the sum of two acute angles is always less than $$ 180^0$$.Hence they cannot form pair of supplementary angles. If two adjacent angles are supplementary, they form a _____. These two angles (140° and 40°) are Supplementary Angles, because they add up to 180°: Notice that together they make a straight angle.

If two angles form a linear pair, then the angles are supplementary. (vii) If two lines are cut by a transversal, (v) Pair of vertically opposite angles are always supplementary. If 2 angles are supplements of congruent angles or of the same angle, then the 2 angles are congruent. Supplementary AnglesTwo angles are called supplementary angles if the sumof their degree measurements equals 180 degrees.Example:These two angles are supplementary. Angles /_1 and /_2 are adjacent (share one side) and acute. ∠ θ and ∠ β are supplementary angles because they add up to 180 degrees. If two lines intersect at a point and if one pair of vertically opposite angles are acute angles, then the other pair of vertically opposite angles are _____. So my question is if both angle 1 and 2 must equal 90 degrees each? If we add 60° and 70°, we get 60°+ 70° = 130° <180° These two angles can be "pasted"together to form a right angle! Cloudflare Ray ID: 616252734e2fc281 If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. WHY??? Answer: No, two acute angles cannot be supplementary angles because according to the definition of acute angle an angle is called an acute angle if its measure is less than 90 0. 5. Answer. ∠ θ and ∠ β are also adjacent angles because, they share a common vertex and arm. When the sum of two angles is 180°, then the angles are known as supplementary angles.
