Question

Which statement is true about the given information?

∠CED measures 45°.
∠CED measures 180°.
∠AEC measures 90°.
∠AEC measures 45°.

Answer 1

The only correct answer would be 
∠AEC measures 90°.

Answer 2

For this case, the first thing to do is observe that the CE line is perpendicular to the AED line.

Therefore, since both lines are perpendicular, then the angle they form is equal to 90 degrees.

Thus, the angle AEC is:

∠AEC = 90º

Answer:

A statement that is true about the given information is:

∠AEC measures 90 °.
