Do you know your Geometry? Can you find the measure of each missing angle (a – m) in the diagram below? (Note: Diagram not drawn to scale.)
Solution:
Some Geometry basic rules:
- Right angle (L ) = 90º
- Straight line = 180º (along each side).
- Triangle = 180º (internal angles).
- Quadrilateral (or 4-sided polygon) = 360º (internal angles).
- Irregular Pentagon (or 5-sided polygon) = 540º (internal angles).
- l, II & lll pairs on a lines represents equal lengths.
