### .  Point Z lies between X and Y. If XY = 77 and ZY = 28, what is the length of XZ?

• A.

105

• B.

38.5

• C.

49

• D.

47

C. 49
Explanation
Point Z lies between points X and Y. We are given that XY = 77 and ZY = 28. To find the length of XZ, we need to subtract ZY from XY. Therefore, XZ = XY - ZY = 77 - 28 = 49.

### Point C is the midpoint of AB.  What segment is congruent to AC?

• A.

CB

• B.

DB

• C.

CD

• D.

AB

A. CB
Explanation
Since point C is the midpoint of AB, it means that AC is half the length of AB. Therefore, segment CB is congruent to AC because they have the same length.

### Point Y is the midpoint of XZ, and point W is the midpoint of XY If XW = 3, what is YZ?

• A.

9

• B.

3

• C.

12

• D.

6

D. 6
Explanation
Since point Y is the midpoint of XZ and point W is the midpoint of XY, we can conclude that YW is equal to WX. Since XW is given as 3, YW and WX both have a length of 3. Therefore, YZ is equal to YW + WX, which is 3 + 3 = 6.

### What is the measure of angle BAD?

• A.

6

• B.

56

• C.

90

• D.

180

B. 56
Explanation
The measure of angle BAD is 56 degrees. This can be determined by using the fact that in a triangle, the sum of all angles is 180 degrees. Since angle BAC is 90 degrees (given in the options), and angle CAD is 34 degrees (180 - 90 - 34 = 56), angle BAD must also be 56 degrees in order for the sum of all angles in the triangle to equal 180 degrees.

### What word best describes the relationship between the two angles below?

• A.

Complementary

• B.

Supplementary

• C.

Linear pair

• D.

None of the above

A. Complementary
Explanation
The word "complementary" best describes the relationship between the two angles below. Complementary angles are two angles that add up to 90 degrees.

Rate this question:

• 7.

### If angle A and angle L are complementary, and mA = x+15, and mL = 34, What is x?

• A.

146

• B.

41

• C.

56

• D.

131

B. 41
Explanation
If angles A and L are complementary, it means that the sum of their measures is 90 degrees. So, we can set up the equation mA + mL = 90. Given that mL = 34, we can substitute this into the equation to get mA + 34 = 90. To solve for mA, we need to isolate it, so we subtract 34 from both sides of the equation, which gives us mA = 90 - 34. Simplifying further, we find that mA = 56. However, the question asks for the value of x, which is equal to mA - 15. Substituting the value of mA, we get x = 56 - 15, which equals 41. Therefore, the correct answer is 41.

### What is the measure of angle DAE?

• A.

52Â°

• B.

128Â°

• C.

90Â°

• D.

25Â°

A. 52Â°
Explanation
The measure of angle DAE is 52Â°. This can be determined by using the fact that angles on a straight line add up to 180Â°. Angle DAE is adjacent to a 90Â° angle, so the remaining angle must be 90Â° as well. Therefore, the angle DAE must be 180Â° - 90Â° = 90Â°.

Rate this question:

• 9.

### What is the measure of angle BAE?

• A.

145Â°

• B.

52Â°

• C.

128Â°

• D.

34Â°

C. 128Â°
Explanation
The measure of angle BAE is 128Â°.

• 10.

### What word below best describes the relationship between angles 4 and 2?

• A.

Linear pair

• B.

Vertical angles

• C.

Supplementary

• D.

Complimentary

B. Vertical angles
Explanation
Vertical angles are formed when two lines intersect. They are opposite angles and are equal in measure. In this case, angles 4 and 2 are opposite angles formed by the intersection of two lines. Therefore, the best word to describe their relationship is "vertical angles".

• B.

155Â°

• C.

65Â°

• D.

55Â°

B. 155Â°
Explanation
The answer is 155Â° because it is the only option that is not a multiple of 5. The other options, 25Â°, 65Â°, and 55Â°, are all multiples of 5.

### What kind of angles are A and E?

• A.

Vertical

• B.

Consecutive interior

• C.

Alternate interior

• D.

Corresponding

D. Corresponding
Explanation
Angles A and E are corresponding angles. Corresponding angles are formed when a transversal intersects two parallel lines. In this case, the lines that are being intersected by the transversal are not mentioned, but we can assume that they are parallel. Corresponding angles are located in the same position relative to the transversal on each of the parallel lines. Therefore, angles A and E are corresponding angles.

• 15.

### What kind of angles are D and E?

• A.

Corresponding

• B.

Alternate interior

• C.

Consecutive interior

• D.

Alternate exterior

B. Alternate interior
Explanation
D and E are alternate interior angles because they are on opposite sides of the transversal line and inside the two parallel lines. Alternate interior angles are congruent, meaning they have the same measure.

### What types of angles are D and F?

• A.

Alternate interior

• B.

Corresponding

• C.

Consecutive interior

• D.

Alternate exterior

C. Consecutive interior
Explanation
Consecutive interior angles are formed when a transversal intersects two parallel lines. In this case, angles D and F are consecutive interior angles because they are on the same side of the transversal and inside the parallel lines.

### All equilateral triangles are also equiangular.

• A.

True

• B.

False

A. True
Explanation
An equilateral triangle is a triangle in which all three sides are equal in length. Since all sides are equal, the angles opposite those sides will also be equal. Therefore, all equilateral triangles have three equal angles, making them equiangular as well.
