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

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

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

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
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 are completely different in size and measurement.

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 angle = 90°
Acute angle < 90°
Obtuse angle > 90° but < 180°
Right is exact, acute is sharp and small, obtuse is wide and larger.
