In the given figure, AB is a straight line and OD ⊥ AB. Is It True Or False? (b) 65°, 125° How To Find The Area Of A Triangle, Given Only Two Angles And One Side? Write. False. Answer to Answer true or false. Choose the correct answer from the given four options (4 to 14): Question 4. False As two acute angles can make a pair of complementary angles. Two right angles can be supplementary Get the answers you need, now! (v) Pair of vertically opposite angles are always supplementary. (d) 40°, 50° True - 90 and 90 degrees. Ans : True 3. Upvote (33) Was this answer helpful? false, W is the vertex . True or False? Fill in the blanks: Complementary angles must be acute. If the sum of two angles is 180 degrees then they are said to be supplementary angles, which forms a linear angle together.Whereas if the sum of two angles is 90 degrees, then they are said to be complementary angles, and they form a right angle together. Now, we know supplementary angles are the angles that add up to 180°. True or False? The interior angles of a triangle add up to 180 degrees. (False) Correct: As the sum of two obtuse angles is greater than 180°. then each pair of alternate interior angles are equal. A pair of vertical angles can be supplementary. Ans : False 4.
