What is a tangent intersecting the segment joining the centers of the two circles?
They are the common tangents to the circles.
Define common internal tangent of 2 circles?
it intersects the segment joining the centers of two circles
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 a common tangent?
A common tangent is a line which is tangent to two (or more) curves.
Is tangent and a circle can have exactly one point in common?
From the definition of tangent, it can ONLY have one point in common called the tangent point.
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.

What is meant by the length of transverse common tangent?
Calculate the length of a direct common tangent of two circles of radii 3cm and 8cm with their centres 13cm apart?soln.-Consider two circles of radii 8 cm and 5 cm with center D and C respectively.It is given that, distance between the center of the circle is 13 cm.∴ DC = 13 cmLet AB be the length of common tangent.From above figure, it is quite clear that AB = CE = x cm (let) andDE = AD - AE = 8 cm - 3 cm = 5 cmIn right triangle DCE, by pythagoras theorem,DC2 = DE2 + CE2⇒ 132 = 52 + x2⇒ x2 = 169 - 25⇒ x2 = 144⇒ x = √144 cm = 12 cmHence, AB = CE = x cm = 12 cmHence, the length of direct common tangent is 12 cm.
What does tangent mean in math?
Tangent, in geometry, is used to describe when figures have only one point in common. In Trig. tangent is applied to triangles.
What is common of tangent?
Common Tangents Some common tangents of two circles can be drawn.You can find that the number of them varies by the condition of the distance and radii of two circles.Using the applet of Common Tangents, try to explore this relation to the common tangents. Using the applet of Common Tangents In this applet you can explore the number of common tangents, dragging to change the radii or to move the circles.The button of@"Init"@is for replacing the figure in the initial state.If you click the button of@"Auto",@the circles are moving automatically, and then you can enjoy their performance.
If a circle of radius 2 is externally tangent to a circle of radius 8 what is the length of their common tangent?
the length of thr direct common tangent will be 2*{1/2 power of (r1*r2)} the answer will be 8 units in this case...
What is the meaning of concentric circles?
They are circles that have a common centre
Is s waves transverse waves?
'S' is a common designator which refers to a transverse body wave.
