All right angles are congruent.All straight angles are congruent.All zero angles are congruent.All the angles of a regular polygon are congruent.Vertical angles (the angles opposite one another when two lines intersect) are congruent.When a transversal crosses parallel lines:Corresponding angles are congruent.Alternative Interior angles are congruent.Alternative Exterior angles are congruent.Finally, any angles with the same measure are congruent.
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
There are no angles they are all obtuse angles
Two opposite right-angles, whose corners share the same crossing point, are vertical angles.
Angles that add to 180 degrees are called supplementary angles, while angles that add to 90 degrees are called complentary angles.
Regular
An equilateral triangle.
Any regular polygon.
An equilateral triangle has 3 equal interior angles each measureing 60 degrees
They are if the triangle happens to be an equilateral one and they're all 60 degrees. Otherwise, no.
Yes. A parallelogram has congruent opposite sides as well as congruent opposite angles.
32.5 degree each
nothing
A congurent half is the same as a line of symetry. It is a half that is the same shape, size and length as the other half
if they are proportional
Yes it does.
a rhombus
