Practical Geometry Formulas — Class 6 ICSE
Construct line segments, angles, perpendicular bisectors, and angle bisectors using compass and ruler.
Key Formulas
Complementary Angles
\angle A + \angle B = 90°
Supplementary Angles
\angle A + \angle B = 180°
Vertically Opposite Angles
\text{Equal in measure}
Angles on a Line
\angle 1 + \angle 2 = 180°
Worked Examples
1Using: Supplementary Angles
If one angle is 65 degrees, find its supplement.
Step 1: Supplement = 180 - 65
Step 2: = 115 degrees.
Answer: 115 degrees
2Using: Vertically Opposite
Two lines intersect. If one angle is 40 degrees, find the vertically opposite angle.
Step 1: Vertically opposite angles are equal.
Step 2: The angle = 40 degrees.
Answer: 40 degrees
