What turn is made by the hour hand when it moves from 3 to 9?
The hour hand moves from 3 to 9, which covers half of the clock’s face. This movement is exactly a half turn. A half turn equals a straight angle of 180°. For example, when the hour hand points at 3, then moves to 9, it shifts from the right side of the clock to the left, creating a straight line.Read more

See lessWhen the minute hand moves by 20 minutes, what fraction of a turn is it?
When the minute hand moves 20 minutes, it has covered one-third of the entire clock face. Since a full turn is 60 minutes, 20 ÷ 60 = 1/3 of a turn. This fraction shows the hand has moved more than a quarter turn (15 minutes) but less than a half turn (30 minutes). So, the movement is exactly one-thiRead more

See lessWhich angle is bigger – two quarter turns or three-eighth turns? Why?
Two quarter turns make a half turn, which equals 180°. Three-eighth turns equal 135° (since 3/8 of 360° = 135°). Comparing these, 180° is greater than 135°. Therefore, two quarter turns are bigger than three-eighth turns. This shows that a straight angle formed by a half turn is larger than the anglRead more

Therefore, two quarter turns are bigger than three-eighth turns. This shows that a straight angle formed by a half turn is larger than the angle formed by moving only three-eighths of a circle.

See lessCan an acute turn ever be equal to a straight angle? Give reason.
An acute angle is defined as being less than 90°. A straight angle, on the other hand, measures exactly 180°. Since an acute angle is always smaller than a right angle and a straight angle is double a right angle, there is no possibility for an acute turn to equal a straight angle. The two types areRead more

Since an acute angle is always smaller than a right angle and a straight angle is double a right angle, there is no possibility for an acute turn to equal a straight angle. The two types are completely different in size and measurement.

See lessWrite the difference between right, acute and obtuse angles.
Angles are defined by their size. A right angle is exactly 90°, like the corner of a square. An acute angle is less than 90°, sharp and narrow, often seen in triangles or pizza slices. An obtuse angle is greater than 90° but less than 180°, appearing wide and open, such as the slope of a roof. TheseRead more

An obtuse angle is greater than 90° but less than 180°, appearing wide and open, such as the slope of a roof. These differences help classify angles in geometry.
More clearly:
Right is exact, acute is sharp and small, obtuse is wide and larger.
