Angles - Coggle Diagram
Angles
Simple Geometry :check:
Vertically Opposite angles are equal
Angles on a straight line add up to 180 degrees
Angles on a point add up to 360 degrees
Parallel lines : :pen:
Corresponding 'F' angles are equal
Alternate 'Z' angles are equal
Co-interior 'C' angles add up to 180 degrees (are corresponding)
