Question

In the adjoining figure, name the following pairs of angles.
1) Obtuse vertically opposite angle.
2) Equal supplementary angles.
3) Adjacent complementary angles.
4) Adjacent angles that do not form a linear pair.​

Answer 1

Answer:

greater than 900 ans 1

ans 2sum of their angles is equal to 180 degrees

ans 3Adjacent Complementary Angles: Two complementary angles with a common vertex and a common arm are called adjacent complementary angles

ans 4All adjacent angles do not form a linear pair. From the above figure we can observe; OX and OY are two opposite rays and ∠XOZ and ∠YOZ are the adjacent angles. Therefore, ∠XOZ and ∠YOZ form a linear pair.
