Where two straight lines cross the "vertically opposite" angles are equal.
Sum of adjacent angles on a straight line.
In a polygon there are no such angles.
Adjacent angles are angles next to each other
they are called supplementary angles. a straight line has 180 degrees each side and two adjacent angles forming 180 degrees are called supplementary angles.
Well, they're called vertically adjacent angles. They have the property that they are supplementary, because the non-adjacent sides form a straight line.
Where two straight lines cross the "vertically opposite" angles are equal.
They are called adjacent angles.
Sum of adjacent angles on a straight line.
They are adjacent angles.
No.
Such angles are called complementary angles.
Two adjacent angles are considered supplementary angles. They aggregate and make an angle that measures 180 degrees.
Vertically Opposite Angles.
In a polygon there are no such angles.
Adjacent Angles
Adjacent angles are angles next to each other
