Question

look at $angle a$ and $angle e$.
complete the statements.
the measure of $angle a$ is $\boldsymbol{square}$ degrees.
the measure of $angle e$ is $\boldsymbol{?}$ degrees.
the angles have $\boldsymbol{?}$

Explanation:

Step1: Identify ∠A's angle type

∠A is formed by vertical side AD and horizontal side AB on the grid, so it is a right angle. A right angle measures $90^\circ$.

Step2: Identify ∠E's angle type

∠E is formed by vertical side EH and horizontal side EF on the grid, so it is also a right angle. A right angle measures $90^\circ$.

Step3: Compare the two angles

Since $m\angle A = 90^\circ$ and $m\angle E = 90^\circ$, the angles are equal in measure (congruent).

Answer:

The measure of $\angle A$ is $90$ degrees.
The measure of $\angle E$ is $90$ degrees.
The angles have equal measure (congruent).
