What are the 2 ways of common external tangent from common internal tangent?
Common external tangents and common internal tangents are two types of tangents that can be drawn between two circles. Common external tangents touch each circle at one point without intersecting the line segment joining the circles' centers, while common internal tangents intersect this line segment. The key difference lies in their geometric relationship to the circles: external tangents do not pass between the circles, whereas internal tangents do. Each type can be determined based on the relative positions and sizes of the circles involved.
How many common external tangent can be drawn to two concentric circles?
If the circles have the same radius then an infinite number, and if they do not, then none.
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 tangents can be drawn from a point on the circumference of a circle?
Only one which is a tangent to that circle.
How many tangents can be drawn on three circles if they dont lie within each other?
if you mean common tangents there can be only 2 tangents
Number of tangents drawn from an external point to a circle?
2
The number of tangents that can be drawn to two nonintersecting circles is?
The answer is four. Wish I could draw a picture.
How many common external tangent can be drawn to two concentric circles?
If the circles have the same radius then an infinite number, and if they do not, then none.
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 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 minor arc whose measure is 80 degrees?
100 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 are circles drawn with?
A compass.
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.
