No, right angles are 90 degrees, supplementary and vertical angles are 180 degrees.
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
Vertical angles can be supplementary angles if the lines are perpendicular and then both of the vertical angles would be 90 digress.
vertical and supplementary
supplementary angles add up to 180 degrees
Supplementary.
No, they are usually not.
If the lines are perpindicular then each pair of vertical angles are supplementary
Yes.
vertical angles and supplementary.
Yes, they can, if they are both 90 degrees.
The answer is {180}
