The diagrams showing pairs of adjacent angles and the given description is shown in the attachments below.
<h3>What are Adjacent Angles?</h3>Adjacent angles are angle that share the same vertex and also has a side in common.
a. An obtuse angle is greater than 90°.
Figure 1 shows a pair of adjacent angles that are obtuse which are ∠ABD and ∠CBD
b. Figure 2 shows two adjacent angles, ∠ABD and ∠CBD whose sum equals 180 degrees.
c. Figure 3 shows two adjacent angles, ∠ABD and ∠CBD whose sum equals 60 degrees.
