Two acute turns (each <90°) can combine to make another acute turn if their total is less than 90°. Example: 30° + 40° = 70° (still acute). But if they sum to 90°, that’s a right angle; if they exceed 90° but are <180°, that’s obtuse. The fan-and-straw activities invite exactly this exploratioRead more

In the house figure, you usually see right angles at window/door corners and wall junctions, acute angles at sharper roof tips and obtuse angles where slanting roof edges meet. Classify each labeled point (A–H) by judging if it’s less than, equal to or greater than a right angle. For more NCERead more

Clockwise movement follows the same direction as the hands of a clock around its face. Anti-clockwise movement is the reverse direction. Recognising these helps describe and measure turns and to operate objects correctly, as shown throughout the chapter’s activities and examples. For more NCERead more
