It doesn't. Its a matter of interpretation.
When drawing the unit circle, we start at x=1, y=0. As we draw, maintaining a radius of 1 from the origin at x=0, y=0, we proceed counter-clockwise. Initially, both x and y are positive. That is quadrant 1. When x becomes negative at x=0, y=1, that is quadrant 2. When y becomes negative at x=-1, y=0, that is quadrant 3. And when x becomes positive again at x=0, y=-1, that is quadrant 4.
So you see, its all in the perspective of which comes first, and in trigonometry, the vector where theta = 0 comes first, not where your eye just happens to scan from left to right.

What does the order of rotational symmetry mean?
if you have a shape in quadrant 1 of a coordinate plane and another shape in quadrant 2, rotate the shape in quadrant 1 to the right 90 degrees. It, when rotated, the shape in quadrant 1 is congruent to the shape in quadrant 2, then they are rotationally symmetrical.
What is the dental formula for a one year old child?
The dental formula for a one-year-old child typically includes 20 primary teeth, with the following distribution: 2 incisors (I) per quadrant, 1 canine (C) per quadrant, and 2 molars (M) per quadrant. This can be represented as 2-1-2 for each quadrant, resulting in a total formula of 2/2 I, 1/1 C, 2/2 M in each quadrant, or 2-1-0-2, which totals 10 teeth in the upper and 10 in the lower jaw.
What is one of the four regions of the coordinate plane determined by the x axis and the y axis?
there is quadrant 1 , quadrant 2 , quadrant 3 , and quadrant 4
How do you find the quadrant of A over 2 if cos A equals 1 over 10 and A is located in quadrant IV?
If A is in quadrant IV, then A/2 is in quadrant II. Yes, the fact than cos(A) is 0.1 means that A is in quadrant I or IV, but it really is not required in order to answer the question. It is superfluous.
