Name a Pair of Vertical AnglesNaming a Pair of Vertical Angles
Vertical Angle Facts
Translated from Latin: verticallyis "overhead" Try to draw an Orange dots. Observe the behaviour of the vertical angles ?JQM and ?LQK. You can see from the above illustration that when two line intersections occur, four angles are made. Every opposite pair is referred to as a vertical angle and is always matching. So are the angles of ?JQM and ?LQK, as well as the angles of ?JQL and ?MQK.
The vertical angles are also referred to as opposite angles. Vertical angles are always either matching or equivalent. Please see JQM and LQK in the above illustration. Total of vertical anglesBoth pair of vertical angles (a total of four angles) always total a full 360° one. Contiguous AnglesIn the above illustration, one of each pair of vertical angles is an adjoining pair of angles and is complementary (adding to 180°).
Example: in the above illustration, m?JQL + m?LQK = 180°. Adapt the above illustration and see for yourself. Around the term "vertical", "vertical" has become a term for "upright", or the opposite of horizontally. The vertical angles are so named because they have a joint knot.

At the intersection of two intersecting axes, they make two sets of opposite angles, A + C and B + D. Another term for opposite angles is vertical angle. The vertical angles are always the same, i.e. they are the same. Adjoining angles are angles that come from the same apex. Adjoining angles divide a beam and do not overlay.
Magnitude of the square in the above figure is the total of the angles A and B. Two angles should complement each other if the total of the two angles is 90°. The two angles are considered additional if the total of the two angles is 180°.
If a crossbeam crosses with two straight line intersections, there are eight angles. Together, the eight angles make up four couples of corresponding angles. The angles 1 and 5 are one of the pair. The corresponding angles are matched. The angles that have the same positions with respect to the parallels and the transverse are all corresponding couples, e.g. 3 + 7, 4 + 8 and 2 + 6.
The angles located in the area between the parallels such as angles 2 and 8 above are referred to as inner angles, while the angles located on the outside of the two parallels such as 1 and 6 are referred to as outer angles. The angles on the opposite sides of the transverse are referred to as alternative angles, e.g. 1 + 8.
Any angles that are either external angles, internal angles, alternating angles or equivalent angles are all mismatched. Above image shows two parallely arranged transversals. Bracket 6 is 65°. ls there another inclination that also measured 65°? Angles 6 and 8 are vertical angles and therefore coincident, i.e. 8 is also 65°.
Corresponding angles 6 and 2 are identical, i.e. angles 2 is 65°. The angles 6 and 4 are alternating outer angles and therefore coincident, i.e. 4 is 65°.
