# what is a terminal ray

What Is A Terminal Ray? Standard Position: An angle is in standard position if its vertex is located at the origin and one ray is on the positive x-axis. The ray on the x-axis is called the initial side and the other ray is called the terminal side.

What is a terminal ray in math? Standard Position: An angle is in standard position if its vertex is located at the origin and one ray is on the positive x-axis. The ray on the x-axis is called the initial side and the other ray is called the terminal side.

What is a terminal side in geometry? Definition of terminal side : a straight line that has been rotated around a point on another line to form an angle measured in a clockwise or counterclockwise direction — compare initial side.

## What is the terminal arm?

Terminal arm: the arm of an angle in standard position that meets the initial arm at the origin to form an angle.

## What is the terminal side of 0?

The initial side is where the angle starts and the terminal side is the ray where the measurement of the angle stops, therefore the terminal side defines the angle and if the vertex is at the origin (0, 0) then the angle will be in Standard Position.

## Which angle has terminal side?

Negative Angles: Negative angles are angles such that their initial side is the positive x-axis and their “terminal” side is determined by turning in a clockwise direction.

## What are the angles of the rays?

An angle is the union of two rays that share a common endpoint. The rays are called the sides of the angle, and the common endpoint is the vertex of the angle. The measure of an angle is the measure of the space between the rays.

## What quadrant does the terminal side lie?

Thus, the terminal side of the angle is in quadrant 3.

## What is the terminal point of 270 degrees?

The terminal side of the angle is on the y-axis. Hence, that angle 270∘ is a Quadrantal Angle. Hope it helps.

## What is the terminal side of 90 degrees?

The angles measuring between 90 and 180 degrees have their terminal sides in Quadrant II. Angles measuring between 180 and 270 have their terminal sides in Quadrant III, and those measuring between 270 and 360 have their terminal sides in Quadrant IV.

## What is the terminal side unit circle?

The terminal side of a -90° angle in standard position is the negative y-axis, which intersects the unit circle at (0, -1). According to the definition of cosecant, csc (-90°) = 1 y or 1 -1, which is -1. Therefore, csc (-90°) = -1.

## Which angle has the same terminal arm as?

Coterminal angles share the same terminal arm and the same initial arm. As an example, here are four different angles with the same terminal arm and the same initial arm. The principal angle is the angle between 0° and 360°. The coterminal angles of 480°, 840°, and 240° all share the same principal angle of 120°.

## Is the terminal side the hypotenuse?

The description of two angles drawn in standard position that share their terminal side. Any part of a graph of a periodic function that is one period long. The side opposite the right angle in any right triangle. The hypotenuse is the longest side of any right triangle.

## What is the point on the terminal side of 135?

You can see that the terminal side of the 135° angle and the x-axis form a 45° angle (this is because the two angles must add up to 180°). This 45° angle, shown in red, is the reference angle for 135°. The terminal side of the 205° angle and the x-axis form a 25° angle. It is 25° because .

## How do you write cosecant?

Cosecant is one of the main six trigonometric functions and is abbreviated as csc x or cosec x, where x is the angle. In a right-angled triangle, cosecant is equal to the ratio of the hypotenuse and perpendicular. Since it is the reciprocal of sine, we write it as csc x = 1 / sin x.

## How many rays are in a pentagon?

Regular Pentagons A regular pentagon must have five congruent sides, five congruent interior angles, and congruent exterior angles: five congruent sides (sides of equal length) five congruent interior angles (each measuring 108° ) five congruent exterior angles of 72°

## How many arrows does a ray have?

A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray. A ray is named using its endpoint first, and then any other point on the ray (for example, →BA ).
