Let’s think and write:

Let’s write whether two acute angles are complementary to each other.

Which of following figures having the sun I adjacent angles as two right angles?

Let's draw a straight line AB and consider a point P on the line AB. Let's erect a ray from P on the straight line AB. As a result two adjacent angles are formed. Now we measure the adjacent angles and examine whether the sum of the measurement of those angles is 180° or not.

Let’s think and write:

Let’s write whether two acute angles are supplementary to each other.

Let’s think and write:

Let’s write whether one acute angle and one obtuse angle which are complementary to each other. Also examine whether two right angles are complementary to each other.
