Do all shapes have 360 degree rotation symmetry?
Yes, if you turn a shape completely around to its original position it will look like its original position because it will be in its original position. For example if i take a trapezoid and turn it 180 degrees it does not look the same as it did before so it does not have rotational symmetry of 180 degrees.
What is a supplementary angle?
Two angles put together to create a 180 degree angle.Supplementary angles add up to 180 degrees as for example the supplementary angle of 120 degrees is 60 degrees because 120+60 = 180 degrees.
How many degrees in a half turn?
there is 180 degree in a half turn
What does a 180 degree angle look like?
Picturing a clock face, a 180 degree angle appears as if the time was 6:00.
What is the supplement of a 65 degree angle?
A pair of supplementary angles total 180 degrees. In this instance, the supplement to a 65 degree angle would be 180 - 65 = 115 degrees.
