# Two Vertical Angles Form a Linear Pair

There are two vertical angles forming a linear pair

Thus the vertical angles are not also a linear pair. The vertical angles have the same dimensions. There are two congruent vertical angles.

## Complementary, additional and vertical angles

Introductory: to other angles. There are three species we study: complementar, supplemental and vertical angles. Complimentary angles are two angles with a total of 90º. Additional angles are two angles with a total of 180º. A vertical angle is two angles whose sides form two sets of opposite beams. The lesson: In the below shown delta the angles A and B2 are complimentary because they have a total of 90º.

Obviously this is because the angles C are 90° and the other two angles must have a total of 90 so that the three angles in the delta together have a total of 180. It' always the truth that the two angles in the right hand side right hand side right hand side right hand side right hand side triangle complement each other. The following figure shows the angles 1 and 2 complementing each other as they form the QP line.

Corresponds to 180º. The following graph shows the angles 1 and 2 as vertical because they form an º and are opposite angles in this º: Use the following chart to show multiple sets of additional and vertical angles. Elbow 1 is vertical with . 2 Angles is vertical with. in either case, these angular pairings form an xt. and are additional because they form the FC line. and are additional because they form the AD line. and are vertical. and are additional because they form the FC line.

The following figure shows the two angles 1 and 2 in addition to angles 3. The vertical angles are the same (have the same dimension). PQR in a right polygon (not shown) with a right polygon angles PQR, assuming we have . Which is the value of x and what are the dimensions of the angles pitch and slope?

The following graph assumes that . Since angles 1 and 2 are vertical, they must have the same dimension.
