Question

5) 360
Explain the following angles.
1) Zero angle
2) The straight angle
3) Right angle
4) Agles in quadrant
5) Co-terminal angles.​

Answer 1

Answer:

1) Zero angle:

An angle with a measure of zero degrees is called a zero angle. If this is hard to visualize, consider two rays that form some angle greater than zerodegrees, like the rays in the . Then picture one of the rays rotating toward the other ray until they both lie in the same line

2) The straight angle:

A straight angle changes the direction to point the opposite way. It looks like a straight line.

3) Right angle:

In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.

4) Angles in quadrant:

Angles in the standard position where the terminal side lies on the x or y axis. For example: 90°, 180° etc. ... A quadrantal angle is one that is in the standard position and has a measure that is a multiple of 90° (or π/2 radians).

5) Co-terminal angles:

Co-terminal angles: are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side. For example, the angles 30°, –330° and 390° are all co-terminal
