Q1. When a transversal cuts two parallel lines, how many pairs of corresponding angles are formed.

• 2
• 3
• 4
• 5

Solution

Four pairs of corresponding angles are formed as follows:

Q2. The angles that form the shape "Z" when two parallel lines are cut by a transversal are

• Corresponding angles
• Alternate angles
• Interior angles
• Exterior angles

Solution

Alternate interior angles and alternate exterior angles form the shape "Z" when two parallel lines are cut by a transversal .

Q3. Supplementary angle of 65^o is :

• 115^o
• 125^o
• 35^o
• 25^o

Solution

Q4. A road crossing two or more roads gives an idea of _________ line.

• transversal
• Equal
• Linear pair
• Perpendicular pair 

Solution

A road crossing two or more roads gives an idea of transversal line.

Q5. Complementary angle of 55^o is

• 65o
• 25o
• 55o
• 35o

Solution

Complementary angle of 55o is 90o- 55o= 35o.

Q6. What is the difference between the measures of a straight angle and a right angle?

• 45^o
• 60^o
• 100^o
• 90^o

Solution

Q7. In a linear pair of angles if both angles are equal then the measure of each angle is

• 60^o
• 50^o
• 90^o
• 120^o

Solution

The sum of angles forming a linear pair is 180^o. When both the angles are equal, Each angle =  = 90^o

Q8. The sum two angles is 90o then the angles are called:

• Supplementary angles
• Reflex angles
• Complete angle
• Complementary angles

Solution

The sum two angles is 90o then the angles are called complementary angles.

Q9. How many line segment/s can be drawn with passing through two given points?

• Exactly one
• Infinite
• Two

Solution

A line segment has two end points, so exactly one line segment can be drawn passing through two points.

Q10. Which of the following statements is not true when a pair of parallel lines is intersected by a transversal?

• Alternate interior angles are equal.
• Co-interior angles are supplementary
• Corresponding angles are not equal
• There are four pair of Vertically opposite angles

Solution

Corresponding angles are not equal

Q11. Which one of the following is a false statement

• A line segment has two end points
• A ray has one end point
• A line has no end point
• Two lines can intersect at infinite points.

Solution

Two or more lines can intersect at only one point.

Q12. The angle whose complement is one-third of its supplement will be

• 90^o
• 135^o
• 180^o
• 45^o

Solution

Sum of complementary angles is 90^o, Sum of supplementary angles is 180^o. Let the required angle be x According to the question 90^o –x =(180^o – x). Solving the equation for x to get x = 45^o.

Q13. Alternate interior angles formed when a transversal cuts two parallel lines, are

• equal
• supplementary
• complimentary
• adjacent

Solution

Alternate interior angles formed when a transversal cuts two parallel lines are always equal.

Q14. Which of the following is not a type of angle?

• Right angle
• Left angle
• Acute angle
• Obtuse angle

Solution

There is no such left angle term.

Q15. How many line segment/s can be drawn with a given initial point?

• Exactly one
• Two
• Three
• Infinite

Solution

Though a line segment has two end points but on fixing only one point, infinite line segments can be drawn from that point to different second point.

Q16. Two Lines intersect

• at a point
• in a line
• at an angle
• in a ray

Solution

Two lines will always intersect at one point only.

Q17. Which of the following is an example of reflex angle?

• 179o
• 91o
• 300o
• 160o

Solution

An angle is called reflex if it is more than 180o and less than 360o.

Q18. The supplement of an angle exceed it by 60^o, then the measure of the angle is

• 60^o
• 120^o
• 180^o
• 90^o

Solution

Let the measure of the angle be x Thus, it's suppliment = 180 - x Accordingly, 180 - x - x = 60 180 - 2x = 60 -2x = 60 - 180 -2x = -120 Thus, x = 60^o

Q19. Reflex angle of 90o is:

• 180o
• 270o
• 300o
• 310o

Solution

Reflex angle of 90o is 360o- 90o= 270o

Q20. Which of the following cannot be the sum of two acute angles?

• 90o
• 150o
• 60o
• 190o
