how do you know which side is adjacent or opposite

by Ms. Meredith Weber Published 3 years ago Updated 2 years ago

To find out which, first we give names to the sides:

  • Adjacent is adjacent (next to) to the angle,
  • Opposite is opposite the angle,
  • and the longest side is the Hypotenuse.

In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle.

Full Answer

What are example adjacent sides?

  • They share a common side
  • They share a common vertex
  • The angles do not overlap
  • Although they share a common side in the centre, the other side is not shared
  • They do not have a common interior point
  • They can be complementary or supplementary

How to find a missing side with cosine?

To solve an SSS triangle:

  • use The Law of Cosines first to calculate one of the angles
  • then use The Law of Cosines again to find another angle
  • and finally use angles of a triangle add to 180° to find the last angle.

What is tan opposite over adjacent?

  • Find the measure of the missing leg. Using the Pythagorean theorem, a2 + b2 = c2, putting in 7 for a and 25 for c, and solving for the missing ...
  • Select names for the acute angles in order to determine the opposite and adjacent designations. ...
  • Form the two tangent ratios by using the values 7, 24, and 25.

Is tan opposite over adjacent?

Sin is equal to the side opposite the angle that you are conducting the functions on over the hypotenuse which is the longest side in the triangle. Cos is adjacent over hypotenuse. And tan is opposite over adjacent, which means tan is sin/cos. What is SOH CAH TOA?

Hypotenuse, opposite, and adjacent (article) | Khan Academy

In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle.

What is adjacent side?

The adjacent side is the non-hypotenuse side that is next to a given angle.

What is the opposite side of a triangle?

Hypotenuse, opposite, and adjacent. In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles.

What is the shortest side of an angle?

The shortest side is the one opposite the smallest angle. If the angle you already know is the shortest one, then the shortest side is opposite it. However, if the angle you already know is the medium one, then the shortest side is adjacent to it.

Which side of a right triangle is the hypotenuse?

The hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle.

Which side is opposite to the right angle?

Hypotenuse is the side that is opposite to the right angle. it is also the longest side in the triangle.

Which side adjacent to eq angle D /eq other than the hypotenuse is?

The side adjacent to {eq}angle D {/eq} other than the hypotenuse is {eq}DE {/eq}.

How to find the hypotenuse of a graph?

Step 1: Take a look at the given diagram and identify the right angle. The side opposite to the {eq}90^circ {/eq} angle. That side will be the hypotenuse.

What is adjacent side?

Definition: Two lines that meet at a polygon vertex. Usually found in triangles and other polygons , two of the sides that meet at a vertex of the polygon are called adjacent sides.

What is the opposite side of a right triangle?

In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles.
