Triangle Angle Trick
Two angles of a triangle are:
50° and 60°
Third angle:
180° − (50° + 60°)
180° − 110°
Answer = 70°
Rectangle Area Trick
Length = 20 cm
Breadth = 10 cm
Area:
20 × 10
Answer = 200 cm²
Circle Circumference Trick
Radius = 7 cm
Circumference:
22 × 22/7 × 7
Answer = 44 cm
Important Geometry Formulas
| Shape | Formula |
|---|---|
| Rectangle Area | Length × Breadth |
| Square Area | Side × Side |
| Triangle Area | ½ × Base × Height |
| Circle Area | πr² |
| Circle Circumference | 2πr |
