Q1 B of 22 Page 70

Let’s think and write:

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


No, acute angles are angles that measure greater than 0° and less than 90°

Supplementary angles are positive angles that add up to 180°.


If you add two acute angles that are each as large as possible, their sum will be less than 180°, so they can’t be supplementary.


Example - 89° + 89° = 178°

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 complementary 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.
