Please enable Cookies and reload the page. And if two acute angles are added then their sum will be less than 180 0 which contradicts the definition of the supplementary angle. Examples ∠ABD and ∠CBD form a linear pair and are also supplementary angles, where ∠1 + ∠2 = 180 degrees. • Supplementary Angles : If the sum of two angles equal to 90°, then it is the supplementary angle. If the exterior sides of 2 adjacent acute angles are perpendicular, then the angles are complementary. Because, we know that the measure of a straight angle is 180 degrees, so a linear pair of angles must also add up to 180 degrees. Two acute angles cannot form a pair of supplementary angles . Performance & security by Cloudflare, Please complete the security check to access. Answer. … Example 2: the angles form a line (linear pair) therefore they are supplementary Example 3: the angles can be non-adjacent as long as their sum is 180° 110°+ 70° = 180° The sum is 180° therefore they are supplementary. So my question is if both angle 1 and 2 must equal 90 degrees each? 3.

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Why? In fact, a linear pair forms supplementary angles. 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. If two angles are right angles, then the angles are complementary. If angle 1 is decreased then, angle 2 will increase with the same measure, so that both the angles still remain supplementary.
