∠ced measures 45°.
∠ced measures 180°.
∠aec measures 90°.
∠aec measures 45°.

Explanation:

Step1: Identify right - angle symbol

The small square at the intersection of lines $AE$ and $CE$ indicates a right - angle.

Step2: Recall angle measure of a right - angle

A right - angle measures $90^{\circ}$. So, $\angle AEC = 90^{\circ}$.

Answer:

$\angle AEC$ measures $90^{\circ}$.
