Topic Content:

  • Angles between Lines and Triangles
    • Angles on a Straight Line
    • Complementary Angles
    • Supplementary Angles
    • Vertically Opposite Angles
    • Angles at a Point
    • Angles in Parallel Lines
    • Angles in Triangles

1. Angles on a Straight Line:

cover course page204
Sum of angles on a straight line is 180°

In the diagram above

⇒ \( \scriptsize \hat{AOB} \:+\: \hat{BOC} \: + \: \hat{COD} = 180^o\)

That is, a + b + c = 180°

2. Complementary Angles:

cover course page205
Complementary angles are defined as two angles whose sum is 90 degrees.

a + b = 90°

Example: a = 40°, b = 50°

3. Supplementary Angles:
