Exercise 8 Page 394

Adjacent angles share a common vertex and one side.

Example Solution: ∠ FAE and ∠ EAD

Practice makes perfect
Before we take a look at the given diagram, let's start by defining adjacent angles.

Adjacent Angles

Two angles that share a common vertex and side.

Now, let's consider the given diagram.

Now, notice that angles ∠ FAE and ∠ EAD share a vertex A and a side AE. Therefore, they are an example of adjacent angles.
