true
True
true or false
Yes, it is true that angle 60 degrees has two edges in the angle parts.
false
True.
True
180 degrees minus interior angle = exterior angle and that the 3 exterior angles of a triangle add up to 360 degrees.
It is true
True only if the two angles are adjacent (i.e. have a point in common). By definition, supplementary angles add up to 180° therefore they are linear pairs, if they are adjacent. Otherwise false. Imagine drawing an angle of 40° at the top of the page and another of 140° at the bottom. These angles are supplementary but not a linear pair.

False. It forms in the Athenosphere!!
true or false ? perpendicular lines intersect at an angle of 45
False

False. There are infinitely many angles at the centre of the circle.
True.
