Question

Name the types of angles shown.

Answer 1

< ABC is a straight angle
no right angles
no complimentary angles
< ABD and < DBC are supplementary angles

Answer 2

Answer:

Option (a) and (d) are correct.

Step-by-step explanation:

 Given : A line segment AC with B a point  on it and DB making an another line segment.

 

We have to name the type of angle shown.

Straight angle : is an angle made by a straight line. Measure of straight angle is 180°

Right angle: is the angle whose measure is 90°

Complementary angles: are two angles whose sum is 90°

Supplementary angles: are two angles whose sum is 180°

Here, ABC forms a straight angle.

and ∠ABD + ∠DBC = 180°

Thus, ∠ABD and ∠DBC forms a pair of supplementary angles.

Option (a) and (d) are correct.
