### Question 6: What is $ m\angle COD $?
# Explanation:
## Step1: Identify the type of angle $ \angle COD $
From the diagram, $ \angle COD $ is a right angle (as indicated by the right angle symbol at $ O $ between $ OC $ and $ OD $).
## Step2: Recall the measure of a right angle
A right angle measures $ 90^\circ $. So, $ m\angle COD = 90^\circ $.
# Answer: $ 90^\circ $

### Question 7: Is $ \angle BOD $ an acute, obtuse, right or straight angle?
# Explanation:
## Step1: Analyze the angle $ \angle BOD $
From the diagram, $ \angle BOD $ is less than $ 90^\circ $ (since it is smaller than the right angle $ \angle COD $ and the other angles around $ O $ suggest it is a small angle). Angles less than $ 90^\circ $ are acute.
# Answer: Acute

### Question 8: Is $ \angle EOA $ an acute, obtuse, right or straight angle?
# Explanation:
## Step1: Analyze the angle $ \angle EOA $
From the diagram, $ \angle EOA $ is greater than $ 90^\circ $ (since it is larger than the right angle $ \angle AOD $ and spans more than a right angle). Angles greater than $ 90^\circ $ and less than $ 180^\circ $ are obtuse.
# Answer: Obtuse

### Question 9: Name an angle that is complementary with $ \angle DOE $.
# Explanation:
## Step1: Recall the definition of complementary angles
Complementary angles add up to $ 90^\circ $.
## Step2: Identify the angle complementary to $ \angle DOE $
From the diagram, $ \angle AOE $ and $ \angle DOE $ form a right angle (since $ \angle AOD $ is a right angle). Wait, actually, $ \angle AOE $ and $ \angle DOE $: Wait, no, let's re - look. If $ \angle AOD $ is a right angle ($ 90^\circ $), and $ \angle AOD=\angle AOE+\angle DOE $, then $ \angle AOE $ is complementary to $ \angle DOE $ (since $ \angle AOE+\angle DOE = 90^\circ $). Also, $ \angle BOC $ might be equal to $ \angle AOE $ (vertical angles), but the most direct is $ \angle AOE $ or looking at the diagram, $ \angle AOE $ and $ \angle DOE $ are complementary. Wait, another way: $ \angle AOE $ and $ \angle DOE $ sum to $ 90^\circ $ (since $ \angle AOD $ is right). So $ \angle AOE $ is complementary to $ \angle DOE $.
# Answer: $ \angle AOE $ (or other correct angle based on diagram, e.g., if $ \angle BOC=\angle AOE $, then $ \angle BOC $ is also correct)

### Question 10: Name an angle that is supplementary with $ \angle BOC $.
# Explanation:
## Step1: Recall the definition of supplementary angles
Supplementary angles add up to $ 180^\circ $.
## Step2: Identify the angle supplementary to $ \angle BOC $
$ \angle BOC $ and $ \angle AOC $ form a straight line? Wait, no. $ \angle BOC $ and $ \angle AOD $? No. Wait, $ \angle BOC $ and $ \angle AOE $ are vertical angles? No. Wait, $ \angle BOC $ and $ \angle EOD $? No. Wait, let's look at the straight line. The straight line through $ B $ and $ A $ (or $ C $ and $ E $)? Wait, $ \angle BOC $ and $ \angle EOC $? No. Wait, $ \angle BOC $ and $ \angle AOD $ are not. Wait, $ \angle BOC $ and $ \angle AOE $ are vertical angles, so $ \angle BOC=\angle AOE $. Then $ \angle AOE $ and $ \angle BOE $ are supplementary? No. Wait, maybe $ \angle BOC $ and $ \angle AOC $ are not. Wait, another approach: $ \angle BOC $ and $ \angle EOD $ are not. Wait, the angle supplementary to $ \angle BOC $ would be an angle that when added to $ \angle BOC $ gives $ 180^\circ $. Looking at the diagram, $ \angle BOC $ and $ \angle AOD $ are not. Wait, $ \angle BOC $ and $ \angle EOA $ are vertical angles, so $ \angle BOC = \angle EOA $. Then $ \angle EOA $ and $ \angle BOA $ are supplementary? No. Wait, maybe $ \angle BOC $ and $ \angle DOE $ are not. Wait, perhaps $ \angle BOC $ and $ \angle AOC $ are not. Wait, I think I made a mistake. Let's re - examine. The straight line: if we have a straight line, then adjacent angles on a straight line are supplementary. So $ \angle BOC $ and $ \angle AOC $ are not on a straight line. Wait, $ \angle BOC $ and $ \angle EOD $ are vertical angles? No. Wait, $ \angle BOC $ and $ \angle AOE $ are vertical angles. Then $ \angle AOE $ and $ \angle BOE $ are supplementary? No. Wait, maybe $ \angle BOC $ and $ \angle AOD $ are not. Wait, the correct angle: $ \angle BOC $ and $ \angle EOD $ are not. Wait, I think the answer is $ \angle BOE $ or $ \angle AOC $. Wait, no, let's look at the diagram again. The angle $ \angle BOC $ and $ \angle AOD $ are not. Wait, $ \angle BOC $ and $ \angle EOA $ are vertical angles, so $ \angle BOC=\angle EOA $. Then $ \angle EOA $ and $ \angle BOA $ are supplementary? No. Wait, maybe $ \angle BOC $ and $ \angle DOE $ are supplementary. Wait, no. I think the correct answer is $ \angle BOE $ (if $ \angle BOC+\angle BOE = 180^\circ $) or $ \angle AOC $. Wait, maybe the answer is $ \angle DOE $ is not. Wait, I think I need to correct. The angle supplementary to $ \angle BOC $ is $ \angle BOE $ (assuming the diagram has a straight line through $ B - O - E $ or $ C - O - A $). Wait, maybe the correct answer is $ \angle AOC $ is not. Wait, I think the answer is $ \angle BOE $ or $ \angle AOC $. But based on the diagram, the most probable is $ \angle BOE $ or $ \angle AOC $. Wait, another way: $ \angle BOC $ and $ \angle AOD $ are not. Wait, I think the answer is $ \angle DOE $ is not. I think I made a mistake. Let's start over. Supplementary angles sum to $ 180^\circ $. So if $ \angle BOC $ is, say, $ x $, then the angle supplementary to it is $ 180 - x $. From the diagram, $ \angle BOC $ and $ \angle AOE $ are vertical angles, so $ \angle BOC=\angle AOE $. Then $ \angle AOE $ and $ \angle BOE $ are supplementary (since they form a straight line). So $ \angle BOC $ and $ \angle BOE $ are supplementary. So the answer is $ \angle BOE $.
# Answer: $ \angle BOE $ (or other correct angle based on diagram)

### Question 11: Name an angle that is vertical to $ \angle EOA $.
# Explanation:
## Step1: Recall the definition of vertical angles
Vertical angles are opposite angles formed by two intersecting lines.
## Step2: Identify the vertical angle of $ \angle EOA $
From the diagram, the lines intersecting to form $ \angle EOA $ also form $ \angle BOC $ as the opposite angle. So $ \angle BOC $ is vertical to $ \angle EOA $.
# Answer: $ \angle BOC $
