how to find the opposite of an angle If you are given an angle alpha the oppossite angle would be alpha 180 If you need to remain in 0 360 then you should take alpha 180 mod 360 what in this case it is simply taking alpha 180 if alpha 180 ge360
The angles that are directly opposite to each other are known as opposite angles They are also termed as vertical angles or vertically opposite angles and are equal to each other Observe the following figure in which lines a and b intersect each other and form two pairs of opposite angles Vertically Opposite Angles are the angles opposite each other when two lines cross Vertical in this case means they share the same Vertex corner point not the usual meaning of up down Example a and b are vertically opposite angles

The answer is to use Sine Cosine or Tangent But which one to use We have a special phrase SOHCAHTOA to help us and we use it like this Step 1 find the names of the two sides we know Adjacent is adjacent to the angle Opposite is opposite the angle and the longest side is the Hypotenuse The tangent function relates a given angle to the opposite side and adjacent side of a right triangle The length of the opposite is given by the formula below In this formula is an angle of a right triangle the opposite is the length of the side opposite the angle and the adjacent is the length of side next to the angle The image below
Vertical angles are a pair of non adjacent angles formed by the intersection of two straight lines and are opposite to each other Vertically opposite angles are equal prove the theorem at BYJU S If you have an angle and the side opposite to it you can divide the side length by sin to get the hypotenuse Alternatively divide the length by tan to get the length of the side adjacent to the angle

In geometry opposite angles are two angles that are located across from each other on a straight line These angles are also sometimes known as vertically opposite angles In this blog post we ll take a closer look at opposite angles how to identify them and some of their key properties How to calculate an angle You can use pattern spotting logic and reasoning to work out angles around straight lines Some facts that are useful to remember are 360 is a full turn 180 is
Connect that angle to the right angle in the triangle and that s the adjacent side Then you know the hypotenuse opposite of the right angle and the adjacent side so the only other side must be the opposite side 1 Angles Add to 180 A B C 180 When you know two angles you can find the third 2 Law of Sines the Sine Rule a sin A b sin B c sin C When there is an angle opposite a side this equation comes to the rescue Note angle A is opposite side a B is opposite b and C is opposite c 3 Law of Cosines the Cosine Rule
