Number of tangents drawn from an external point to a circle?

Ab and ac are tangents to a circle with centre o and radius 5cmif ac equals 12cmfind the perimeter of quadrilateral aboc?
Since AB and AC are tangent to the circle O, it seems that they both are drawn from the same outside point A. As tangents to a circle from an outside point are congruent, AB ≅ BC. Also, a tangent is perpendicular to radius drawn to point of contact. So that OB and OC are congruent radii. Therefore, the perimeter of the quadrilateral ABOC equals to P = 2(12 cm) + 2(5 cm) = 34 cm.
How many diagonals does a circle have?
If you are referring to the segment passing through the center of the circle and touching the circumference of the circle then it's the diameter of the circle.There can be infinite diameters drawn inside a circle.
How many diameters of a circle can be drawn?
There are infinite diameters within a circle.
What circle is the largest circle that can be drawn around a sphere such as a globe?
general astronomy
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.
How many tangents can be drawn to a circle containing a point inside the circle?
None can. A tangent is a line that touches a circle at only one point. If it wentthrough a point inside the circle, then it would have to touch the circle at twopoints ... one on the way in and another one on the way out.
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.
How many parallel tangents can be drawn to a circle?
An infinite amount

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 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 200 degrees?
The angle between the two tangents is 20 degrees.
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
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
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.
Why do the tangents drawn at the ends of a chord of a circle make equal angles with the chord?
Because in effect an isosceles triangle has been constructed and the base angles are always equal.
