Test: Lines, Angles & Triangles - 2 - Question 1

When it is 10 : 30, what kind of angle is formed by the hands of the clock?

Detailed Solution for Test: Lines, Angles & Triangles - 2 - Question 1

Here the angle between any two consecutive numbers in a clock is 30.
Now we know that when time is 30 minutes, then the minute clock will be at 6.
And when time is 10:30, the hour clock will be between 10 and 11. Let us draw a clock here for better understanding.

Now the number of parts (number) between 6 to 10 are 4. So an angle between 6 and 10 will be 4×30=1204×30=120. Similarly, there are 5 parts between 6 to 11. So the angle between 6 and 11 will be 5×30=1505×30=150.
Hence our angle will be between 120 and 150120 and 150∘ and it will be exactly in middle of 10 and 11, so angle will be equal to 120+1502=2702=135120+1502=2702=135.
Hence our required angle between the hands of a clock as 10:30 is 135.
Since 135 is greater than 90 so it is an obtuse angle.

Detailed Solution for Test: Lines, Angles & Triangles - 2 - Question 3

5 angles are less than a right angle.

Test: Lines, Angles & Triangles - 2 - Question 4

An angle which measures more than 0° but less than 90° is called ____.

Detailed Solution for Test: Lines, Angles & Triangles - 2 - Question 4

an angle which measures more than 0 degree and less than 90 degree is called an acute angle..

Test: Lines, Angles & Triangles - 2 - Question 5

Which of the following is NOT drawn in the diagram?

Detailed Solution for Test: Lines, Angles & Triangles - 2 - Question 5

Except line segment CD, ray BD, line AD and ∠B is clearly seen in the diagram.

Hence the correct answer is option D.

Test: Lines, Angles & Triangles - 2 - Question 6

Danish drew an angle as shown here. Manish drew an angle that was twice the measure of Danish's angle. What was the measure of Manish's angle?

Detailed Solution for Test: Lines, Angles & Triangles - 2 - Question 6

Measure of angle drawn by Danish = 40
∴Measure of angle drawn by Manish = 2×40=80

Test: Lines, Angles & Triangles - 2 - Question 7

How many of the given figures have perpendicular lines?

Detailed Solution for Test: Lines, Angles & Triangles - 2 - Question 7

4

All the figures as shown in above have perpendicular lines
Hence the correct answer is option D.

Test: Lines, Angles & Triangles - 2 - Question 8

How many angles are less than 90  in the given figures?

Detailed Solution for Test: Lines, Angles & Triangles - 2 - Question 8

There are 3 acute angles in the given figures. 

Test: Lines, Angles & Triangles - 2 - Question 9

In the given figure, which line is perpendicular to AB?

Detailed Solution for Test: Lines, Angles & Triangles - 2 - Question 9

According to the given figure line EF and line AB meet each other at right angle

∴ Line EF is perpendicular to line AB
Hence the correct answer is option B

Test: Lines, Angles & Triangles - 2 - Question 10

What is the approximate measure of this angle in degrees?

Detailed Solution for Test: Lines, Angles & Triangles - 2 - Question 10

The given angle is a acute angle, so option D and option C is not correct

The approximate value of above angle is 45o, as the angle of 20o would be very small than the given angle

Hence the correct answer is option B.
