Look around you! Lines and angles are everywhere - in buildings, books, roads, and even in sports!
Real World Examples:
• Cricket stumps form straight lines
• Book corners make 90° angles
• Road intersections create angles
• Clock hands make different angles
Railway Tracks:
Parallel lines - they never meet
Like railway tracks or notebook lines
Cross Roads:
Intersecting lines - they cross each other
Like roads crossing at junctions
Right Angle (90°):
Book corners, door edges, L-shaped roads
Like the letter "L"
Acute Angle (<90°):
Slice of pizza, piece of pie, sharp corner
Smaller than a right angle
Obtuse Angle (>90°):
Open book, fan blades, wide corner
Bigger than a right angle
In this chapter, we will learn:
