The idea is that three lines coming out from the center point of a circle (three radii) form three angles -- imagine, for an easy example, the Mercedes-Benz logo. Then the question is: if two of the angles each measure 130 degrees, what does the third angle measure?
Well, the first two together measure 260 degrees.
So, how many degrees in a circle overall are left, once 260 are taken out? There are 360 degrees in a circle, so the answer is 100.
45 degree anglestwo 45degree angle
The 3 interior angles are 90 degrees, 45 degrees and 45 degrees
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.

degrees
Degrees are used to measure angles.
64 degrees because the total of the angles has to equal 360 degrees for it to be a hexagon.
They measure 105 degrees each.
Angles that measure less than 90 degrees are called acute angles. Right angles measure exactly 90 degrees and obtuse angles are greater than 90 degrees.
