What is the relationship between a circle and an angle?
An angle is the measurement of two lines drawn from the centre of a circle. A circle is 380 degrees. So in an angle of 90 degrees, one line would be vertical at 0 degrees, and the second line would be horizontal at 90 degrees. So the relationship is that you can't have one without the other.
What is the measure of the angle formed by two tangents drawn to a circle from an external point if they intersect a minor arc whose measure is 150 degrees?
Assuming the measure of the arc refers to the angle at the centre of the circle, the answer is 180 - 150 = 30 degrees.
What is the measure of the angle formed by two tangents drawn to a circle from an external point if they intersect a major arc whose measure is 200 degrees?
The angle between the two tangents is 20 degrees.
What is the measure of the angle formed by two tangents drawn to a circle from an external point if they intersect a minor arc whose measure is 80 degrees?
100 degrees
How many degrees is on a circle?
A circle has a total of 360 degrees. This measurement is used to describe the angle formed at the center of the circle when two radii are drawn to the circumference. Each degree represents a fraction of the circle, allowing for precise measurements of angles and rotations.
When drawn on a circle the angle 472 degrees is drawn in the same position as?
There are 360 degrees in a full circle, so 472 must be 360 + 112 = 472 degrees. So the line on the circle is in the same position as 112 degrees!

If a line is tangent to a circle what angle is formed if a radius is drawn to the point of tangency?
90 degrees. QED.

What is the measure of an angle formed by a tangent and a secant drawn to a circle from an external point if it intercepts arcs whose measures are 70 and 30?
20 degrees
Which circle is drawn on the map at 67 degrees N latitude?
The Arctic Circle is around 66.5 degrees north.
How many degrees are in the arc of a circle?
A circle contains 360 degrees. Draw a circle, add a radius to any point on it, and then rotate the radius completely around. After it has returned to the point it initially intersected the curve, the radius will have rotated through 360 degrees.(another explanation, maybe no better.)A complete circle measures 360 degrees, so a half-circle is 180 degrees, a quarter-circle is 90 degrees and so forth. Another way to look at it is in terms of the central angle formed by the radii drawn from each endpoint of the arc - the measure of the arc in degrees is the same as the measure of this central angle in degrees.
What is a square in a right angle?
The square drawn in a right angle simply is to indicate that the angle is, indeed, 90 degrees.
How do you transfer percentages into a circle graph?
Start by plotting a base line from the center to the 12:00 position (imagine the circle is a clock face). The first plot will be some angle of rotation (clockwise) from this line. Determine this angle of rotation by multiplying (percentage/100) x 360 degrees. Say the percentage was 40% you would multiply 0.40 x 360 degrees = 144 degrees. Take your protractor and draw a line from center at a 144 degree angle from the first (12:00) line. Proceed with the remaining values using that previously drawn line as the base line for the next angle of rotation.
