What is an example of a radius in math?
A radius is a line drawn from the centre of a circle to the edge of that circle. It is half the length of the diameter of the circle.
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.
A compass draws all points that are equidistant from a fixed point thereby creating a locus of points for a circle?
A circle is the locus of all points equidistant from a given point, which is the center of the circle, and a circle can be drawn with a compass. (The phrase "locus of points for a circle" does not seem to be conventionally defined.) or true
How many circle can be drawn passing through two points?
There are infinite circles which can be drawn with 2 defined points.. Because if we have 2 points then we can draw infinite equal intersecting lines in infinite directions, These intersecting lines are the radii of the circles. Like : we have 2 points You can draw infinite isosceles triangles as taking the line joining the points For example (activity) : we have 2 points A, B so let's join A and B which will make line AB and so let's take another point C and place that point in such a way that AC = AB and we observe that there are infinite points which can be placed in such a way like how we marked C. Now draw a circle with center C and radius A, we will observe that the circle also cuts through B and so as we have infinite points like C, so we can have infinite circles ..... And so we conclude that infinite circles with different radii can be drawn through two defined distant points ...
What is the chord of a circle?
Take any circle and draw a straight line through it anywhere so that the line intersects the circle at two distinct points. The segment between the two points on the circle is the chord. A diameter, that is, a line segment through the center, could be a chord. But any shorter segment drawn through the circle and intersecting the circle at those two distinct points is a chord. It's just that simple. Need a link? You'll find one below.
Is the tangent to a circle perpindicular to the radius drawn to the point of tangency?
Yes it is. Great work !
Is the tangent of a circle is parallel to the radius drawn to the point of tangency?
Yes it is. Great work!
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 does the radius-tangent theorem state?
The radius-tangent theorem states that a radius drawn to the point of tangency of a circle is perpendicular to the tangent line at that point. This theorem is based on the fact that the radius of a circle is always perpendicular to the tangent line at the point where the tangent touches the circle. This relationship is crucial in geometry and helps in solving various problems related to circles and tangents.
Is The point at which a tangent line meets a circle is called the point of tangency.?
Yes, the point at which a tangent line intersects a circle is indeed called the point of tangency. At this point, the tangent line touches the circle at exactly one location, and it is perpendicular to the radius drawn to that point. This relationship is fundamental in geometry, particularly in the study of circles and tangents.
Line touches a point on the circumference of the circle?
When a line touches a point on the circumference of a circle, it is referred to as a tangent. A tangent to a circle is a straight line that intersects the circle at exactly one point, known as the point of tangency. At this point, the tangent is perpendicular to the radius drawn to the point of tangency. This unique relationship defines the geometric properties of tangents in relation to circles.
What is the measure of an arc intercepted by an angle formed by a tangent and a chord drawn from the point of tangency if the angle measures 40?
4/9*pi*r where r is the radius of the circle.
Point of intersection between a tangent and circle?
A line tyhat's tangent to a circle intersects the circle in exactly one single point. The radius drawn to that point is perpendicular to the tangent.
How many tangents can be drawn to a circle containing a point inside a circle?
No tangent No tangent
What is the measure of an arc intercepted by an angle formed by a tangent and a chord drawn from the point of tangency if the angle measures 40 degrees?
150
How do you find the length of a radius drawn from the center of the circle to a tangent?
It is the same length from the centre to any point on the circumference so just measure it
How many tangents can be drawn from a point on the circumference of a circle?
Only one which is a tangent to that circle.
