What is the ratio of the hypotenuse to the opposite side?
Let us start with some definitions. We will call the ratio of the opposite side of a right triangle to the hypotenuse the sine and give it the symbol sin. The ratio of the adjacent side of a right triangle to the hypotenuse is called the cosine and given the symbol cos.
How do you find the sine of an angle?
In any right angled triangle, for any angle:
- The sine of the angle = the length of the opposite side. the length of the hypotenuse.
- The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
- The tangent of the angle = the length of the opposite side. the length of the adjacent side.
What is OPP over HYP?
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. The hypotenuse of a right triangle is always the side opposite the right angle.
Is sin opposite over hypotenuse?
Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse .

How do you solve a sine triangle?
How to Calculate the Sine of an Angle
- Identify the hypotenuse. Where’s the right angle?
- Locate the opposite side. Look at the angle in question, which is.
- Label the adjacent side. The only side that’s left, side k, has to be the adjacent leg.
- Locate the two sides that you use in the trig ratio.
- Find the sine.
How do you get the OPP HYP?
Futhermore, the sin(x) / cos(x) = (opp/hyp) / (adj/hyp) = opp / adj = tan(x). Therefore, the tangent function is the same as the quotient of the sine and cosine functions (the tangent function is still fairly handy)….Math2.org Math Tables:
| sin(q) = opp/hyp | csc(q) = 1/sin(q) |
|---|---|
| tan(q) = sin(q)/cos(q) | cot(q) = 1/tan(q) |
What do the abbreviations OPP adj and Hyp represent?
The abbreviations opp, adj, and hyp represent the three sides of a right triangle. opp: the length of the side opposite theta. adj: length of the side adjacent to theta. hyp: length of the hypotenuse – the side opposite the right angle. GSP Activity. 1. Begin with a segment. 2. Rotate the segment to create a 30 degree angle.
What is oppopp and Hyp?
opp: the length of the side opposite theta. adj: length of the side adjacent to theta. hyp: length of the hypotenuse – the side opposite the right angle. GSP Activity. 1. Begin with a segment. 2. Rotate the segment to create a 30 degree angle.
What is the value of H Y P in a triangle?
In a unit circle h y p = 1, so we get y = s i n θ, where y is the opposite side. In other triangles the value of h y p is other than 1.
What does oppopp mean in math?
opp: the length of the side opposite theta. adj: length of the side adjacent to theta. hyp: length of the hypotenuse – the side opposite the right angle. GSP Activity. 1. Begin with a segment.
