FAQs
Question: What are the different types of angles I should know for exams? Answer: You should be familiar with acute, obtuse, right, and straight angles, as well as their properties and applications.
Question: How do parallel lines affect angle relationships? Answer: Parallel lines create specific angle relationships such as corresponding angles being equal and alternate interior angles being equal, which are crucial for solving problems.
Now that you understand the importance of "Angles and Parallel Lines", it's time to put your knowledge to the test! Solve practice MCQs and important questions to solidify your understanding and excel in your exams.
Q. If angle 1 and angle 2 are alternate exterior angles formed by a transversal intersecting two parallel lines, what is true about their measures?
A.
They are equal.
B.
They are supplementary.
C.
They are complementary.
D.
They are not related.
Solution
Alternate exterior angles are equal when two parallel lines are cut by a transversal.
Q. If two lines are parallel and a transversal creates an angle of 40° with one of the lines, what is the measure of the corresponding angle on the other line?
A.
40°
B.
140°
C.
180°
D.
90°
Solution
Corresponding angles are equal, so the corresponding angle is also 40°.
Q. If two parallel lines are cut by a transversal and one of the corresponding angles measures 30°, what is the measure of the other corresponding angle?
A.
30°
B.
150°
C.
60°
D.
90°
Solution
Corresponding angles are equal, so the other corresponding angle also measures 30°.
Q. In a pair of parallel lines cut by a transversal, if one of the interior angles is 120°, what is the measure of the other interior angle on the same side of the transversal?
A.
60°
B.
120°
C.
180°
D.
90°
Solution
The two interior angles on the same side of the transversal are supplementary, so the other angle is 180° - 120° = 60°.
