Given that eb bisects cea, which statements must be true? check all that apply.

Consider all options:

1. m∠CEA=90°. This option is true, because

2. ∠CEF is straight angle, then m∠CEF=180°. If bisects right angle ∠CEA, then

m∠CEB=m∠BEA=45°.

Therefore,

m∠BEF=m∠BEA+m∠AEF=45°+90°=135°.

Then m∠CEA+m∠BEF=90°+135°=225° ≠ 180°=m∠CEF.

This option is false.

3. m∠CEB=45° and m∠CEA=90°, then m∠CEB≠2m∠CEA.

This option is false.

4. From the part B you can see that m∠BEF=135°. This option is true.

5. ∠CEF is straight angle, this option is true.

6. Since then ∠AEF is right angle. This option is true.

true options are 1, 4, 5 and 6.
