Choose the option in which both the figures show equal angles between minute hand and hour hand of clock.

• Figure B and C

• Figure A and B

• Figure A and C

• Figure A and D

Answer explanation

Figure A and C shows 20 minutes gap between minute hand and hour hand. Hence these figure show equal angle. Figure B has 25 minutes gap and figure D has 15 minutes gap. So option 3 is correct answer.

Find the measure of ∠PQR from given figure?

• 60°

• 120°

• Both 1 and 2

• None of these

Answer explanation

Option 2 is correct as ∠PQR can be measured from left side to right side in clockwise direction on outer scale. Hence 120° is the measure of angle ∠PQR.

Line segment PQ is perpendicular to line segment AB and they both intersect at point T. If point D is in interior of ∠BTQ then what is the type of angle ∠ PTD?

• Obtuse angle

• Complete angle

• Straight angle

• Reflex angle

Answer explanation

As line segment PQ is perpendicular to AB, hence ∠PTB = 90° and point D is in interior of angle ∠ BTQ . ∠PTD is greater than ∠ PTB. hence ∠ PTD is an obtuse angle.
