Angles

Angles in a triangle add up to180'

Angles in a quadrilateral add up to 360'

Angles on a straight line add up to 180'

Angles at a point add up to 360'

To find angles in polygons-  Divide into triangles, how many triangles x 180, take all of the angles in the shape and then =

Alternate angles are equal - F shape

Corresponding angles are equal - Z shape
