Use the digram below to fill in the sentence with the correct angles … (Technically, these two lines need to be on the same plane) Vertical angles are congruent (in other words they have the same angle measuremnt or size as the diagram below shows.) If two angles are vertical angles, then they’re congruent: ∠ 1 = ∠3 ∠ 2 = ∠ 4. In the figure, ∠ 1 and ∠ 2 are adjacent angles. Theoretical Description of Adjacent Angles and Vertical Angles: Adjacent angles are two angles that have common arm and common vertex. They do not have to even be related to each other in any way, they can be drawn independently. Vertical Angles - Two lines intersect each other and form angles. Two angles are said to be supplementary when the sum of both angles is 180° degrees. Hence, the missing values are calculated. In a right triangle, the two acute angles will always be complementary. Since the angle that is opposite the 43° angle is supplementary to the 137° angle, then it must also be 43°. Which statement is the contrapositive of: If two angles are vertical angles, then they are not adjacent angles.

When two lines intersect each other at one point and the angles opposite to each other are formed with the help of that two intersected lines, then the angles are called vertically opposite angles. Vertical angles are always congruent, which means that they are equal. If two angles are non-adjacent and formed by intersecting lines, then they are vertical angles. In corresponding angles, two lines are crossed by another line and the matching corners are called corresponding angles. If the two supplementary are adjacent to each other then they are called linear pair. Hence, complementary angles are also called opposite angles. : Adjacent angles Vertical angles are one of the most frequently used things in proofs and other types of geometry problems, and they are one of the easiest things to spot in a diagram.
