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.
A tangent circle passes always through the center of the circle?
A line joining the centres of two tangent circles also passes through the point of tangency.
What is a tangent intersecting the segment joining the centers of the two circles?
They are the common tangents to the circles.
Is the center of a circle the point of intersection for two concentric circles?
Concentric circles are the circles with the same center therefore they do not cross with each other as the "center is not considered a point on the circle". An exception would be two circles that are concentric and have the same radius, in which case the circles are indistinct and every point of the circles is an intersection.
Can two circles be tangent to the same line at the same point?
Sure. They would have one of two appearances. Either they look like a figure ' 8 ' with a line across the middle, or else they look like two soap bubbles, one inside the other, hanging from the line.
Are tangent circles two circles that are tangent to the same line at the same point?
Yes.
What is a tangent internally?
Two circles in the same plane are externally tangent if they intersect in exactly one point and their intersection of their interiors is empty.
What are two coplanar circles that intersect at exactly one point?
Tangent circles.
A line that is tangent to two circles?
... touches each circle in exactly one point on each circle. given any two circles where none is entirely inside or inside and tangent to the other, there are at most four straight lines that are tangent to both circles.
How do you make transverse common tangent to two circles?
You join the centres of the two circles. Divide this line in the ratio of the two radii. Draw the tangent from this point to either circle and extend it to touch the other circle.
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.
A tangent circle passes always through the center of the circle?
A line joining the centres of two tangent circles also passes through the point of tangency.
What are Two circles with the same centre point called?
Concentric circles
Does a tangent circle pass through the center of the circle?
If the tangent circles are outside of one another, then neither passes through the center of the other. If one circle is within the other, then the inner tangent circle might contain the center point of the larger circle. There will be infinitely many inner tangent circles that do not.
What is a tangent intersecting the segment joining the centers of the two circles?
They are the common tangents to the circles.
When are two coplanar circles concentric?
When the centers of both the circles are at the same point.
