Q. If a circle has a radius of 4 units, what is its area?
A.
16π
B.
8π
C.
12π
D.
20π
Solution
The area of a circle is given by the formula A = πr². Thus, A = π(4)² = 16π.
Q. If two lines are parallel and the measure of one of the interior angles is 45 degrees, what is the measure of the other interior angle on the same side of the transversal?
A.
45 degrees
B.
135 degrees
C.
90 degrees
D.
180 degrees
Solution
Interior angles on the same side of the transversal are supplementary, so 180 - 45 = 135 degrees.
Q. If two lines are parallel and the transversal creates an angle of 30 degrees with one of the lines, what is the measure of the alternate interior angle?
A.
30 degrees
B.
60 degrees
C.
150 degrees
D.
180 degrees
Solution
Alternate interior angles are equal, so the alternate interior angle is also 30 degrees.
Q. If two lines are parallel and the transversal creates an angle of 75 degrees with one of the lines, what is the measure of the corresponding angle on the other line?
A.
75 degrees
B.
105 degrees
C.
90 degrees
D.
180 degrees
Solution
Corresponding angles are equal when two parallel lines are cut by a transversal.
Q. If two triangles are similar and the lengths of the sides of the first triangle are 3, 4, and 5, what are the lengths of the sides of the second triangle if the ratio of similarity is 2:1?
A.
6, 8, 10
B.
3, 4, 5
C.
1.5, 2, 2.5
D.
4, 5, 6
Solution
If the ratio of similarity is 2:1, then the sides of the second triangle are 2 times the sides of the first triangle: 3*2, 4*2, 5*2 = 6, 8, 10.
Q. In a coordinate plane, what is the distance between the points (3, 4) and (7, 1)?
A.
5 units
B.
4 units
C.
3 units
D.
6 units
Solution
The distance between two points (x1, y1) and (x2, y2) is given by the formula √((x2 - x1)² + (y2 - y1)²). Thus, distance = √((7 - 3)² + (1 - 4)²) = √(16 + 9) = √25 = 5 units.
