• 1.

### Angles 3 and 4 are __________________.

• A.

Complimentary

• B.

Supplementary

• C.

Vertical

• D.

Corresponding

C. Vertical
Explanation
Angles 3 and 4 are vertical angles. Vertical angles are formed when two lines intersect. They are opposite each other and have equal measures. In this case, angles 3 and 4 are opposite each other and have the same measure, making them vertical angles.

### If the angle shown in pink is labled 45 degrees, what is the measurement of angle 1?

• A.

45 degrees

• B.

135 degrees

• C.

90 degrees

• D.

Unable to determine

A. 45 degrees
Explanation
Angle 1 is the same as the angle shown in pink, which is labeled as 45 degrees. Therefore, the measurement of angle 1 is also 45 degrees.

Rate this question:

• 3.

### Angles 1 and 2 are ___________ angles.

• A.

• B.

Exterior Consecutive Angles

• C.

Corresponding Angles

• D.

Vertical Angles

C. Corresponding Angles
Explanation
Angles 1 and 2 are corresponding angles. Corresponding angles are formed when a transversal intersects two parallel lines. In this case, angles 1 and 2 are formed by the transversal intersecting two parallel lines. Corresponding angles are congruent, meaning they have the same measure.

• 4.

### In geometry, what type of angle measures exactly 90 degrees?

• A.

Acute angle

• B.

Obtuse angle

• C.

Right angle

• D.

Reflex angle

C. Right angle
Explanation
Right angle: This is the correct answer. A right angle measures exactly 90 degrees, forming a perfect L-shape, like the corner of a square or rectangle.

• 5.

### When you add angle 1 and angle 4's measurements, you get how many degrees? (Give a number.)

180
Explanation
When you add the measurements of angle 1 and angle 4, you get a sum of 180 degrees.

Rate this question:

• 6.

• A.

1,2

• B.

2,3

• C.

4,5

• D.

1,6

D. 1,6
• 7.

• A.

4,5

• B.

6,7

• C.

2,8

• D.

1,8

A. 4,5
• 8.

### Adjacent angles share a _______ and have a common side. (One word - spelling counts!)

vertex
Explanation
Adjacent angles share a vertex, which is the point where the two angles meet. They also have a common side, meaning that one side of each angle is the same.

Rate this question:

• 9.

### Two angles whose measurements add up to 90 degrees are said to be _____________.

• A.

Congruent

• B.

Comparable

• C.

Complimentary

• D.

Critical

C. Complimentary
Explanation
Two angles whose measurements add up to 90 degrees are said to be complimentary. The term "complimentary" is used in geometry to describe angles that together form a right angle. The word "complimentary" in this context is spelled with an "i" instead of an "e" because it is derived from the Latin word "complementum," meaning completion or complement. Therefore, when two angles are complimentary, they complete each other to form a right angle.

### True or False. Think about this one....Assuming the lines are parallel in this diagram, if you added ALL the Alternate Interior Angles together, and then you added the measurements of ALL the Alternate Exterior Angles together, the 2 total measurements would be equal to each other.

• A.

True

• B.

False

A. True
Explanation
If the lines in the diagram are parallel, then the alternate interior angles and alternate exterior angles are congruent. Therefore, if you add all the measurements of the alternate interior angles together and add all the measurements of the alternate exterior angles together, the two totals will be equal to each other. This is because alternate interior angles and alternate exterior angles are formed by a transversal intersecting parallel lines, and they are always congruent.

• 11.

### What term best describes angles 7 and 6.

• A.

Acute

• B.

Obtuse

• C.

Scalene

• D.

Congruent

D. Congruent
Explanation
The term "congruent" best describes angles 7 and 6 because congruent angles have the same measure. This means that angles 7 and 6 have the exact same angle measure, making them congruent to each other.

Rate this question:

• 12.

### True or False. Angles 4 and 7 are congruent.

• A.

True

• B.

False

B. False
Explanation
The question states that angles 4 and 7 are congruent. However, since the answer is false, it means that angles 4 and 7 are not congruent.
