JSS2 Mathematics Third Term: Angles in a Polygon
Topic: ANGLES IN A POLYGON Angles between lines If a line is split into 2 and you know one angle you can always find the other one. Example: If we know one angle is 45° what is angle “a” ? Angle a is 180° − 45° = 135° This method can be used for several angles on one side of a straight line. […]
