How many tangents can be drawn from a single point?

Two tangents can be drawn from a point outside a circle to the circle. The answer for other curves depends on the curve.


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.


How many parallel tangents can be drawn to a circle?

An infinite amount


How many tangents can be drawn to a circle containing a point inside a circle?

No tangent No tangent


How many tangents can be drawn from a point on the circumference of a circle?

Only one which is a tangent to that circle.


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 tangents can be drawn to a circle containing a point outside the circle?

Any tangent must contain a point outside the circle. So the answer to the question, as stated, is infinitely many. However, if the question was how many tangents to a circle can be drawn from a point outside the circle, the answer is two.


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.


How many tangents can be drawn to a point on a circle?

Always one for sure, and never more than one.

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 243 and the minor arc measures 117?

63o. Join the points where the tangents touch the circle to its centre to form a quadrilateral (two meeting tangents and two radii). These angles are both 90o, summing to 180o. Thus the other two angles - the one at the centre of the circle and the one where the tangents meet - sum to 360o - 180o = 180o (they are supplementary). The centre angle is given as 117o (the minor arc), so the angle where the tangents met is 180o - 117o = 63o.


The number of tangents that can be drawn to two nonintersecting circles is?

The answer is four. Wish I could draw a picture.
