1. 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

  2. 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

    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 angle formed by moving only three-eighths of a circle.

  3. 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.

  4. 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

    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. 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.

  5. Turning half a circle makes Padma face the location directly opposite the toy shop on the given layout. The same final facing can be achieved by a half turn anti-clockwise or by making two right-angle turns in succession (clockwise or anti-clockwise). This reinforces that two right angles equal oneRead more

    Turning half a circle makes Padma face the location directly opposite the toy shop on the given layout. The same final facing can be achieved by a half turn anti-clockwise or by making two right-angle turns in succession (clockwise or anti-clockwise). This reinforces that two right angles equal one straight (half) turn.
