Determine two coterminal angles positive and negative

👉 Learn the basics of co-terminal angles. An angle is a figure formed by two rays that have a common endpoint. The two rays are called the sides of the angle while the common endpoint is called the vertex of the angle. We measure angles starting from the positive x-axis, i.e. the initial side of an angle measure is usually the positive x-axis. The angle measured in the anti-clockwise direction is called a positive angle while a negative angle is measured in the clockwise direction.

Two or more angles are said to be co-terminal when they have the same initial and terminal sides. Coterminal angles are found by adding/subtracting 360 degrees (for degree angle measure) or 2pi (for radian angle measure) to/from the given angle.

Im using your videos to help through my trig class! Ive never been good at math but thankfully I have good trig professor. With her lectures and your videos at ( that I watch on my own at home) im actually understanding where the magic happens! thank you!!!

[Bumpin.Lead]

Hey man, your videos have really helped me with my trigonometry. Without this extra instruction, since I got none from my teacher, I would have definitely failed, and worst of all not be prepared for the EOC. Much thanks bro!!!!
