draw two concentric circles of radius 2cm and 3cm draw common tangents to each circles from point 7cm from center
Answers
Answer:
Two concentric circles of radius 2cm and 3cm draw common tangents to each circles from point 7cm from center.
Step-by-step explanation:
Circles having a central point are known as concentrated circles. An annulus is the area positioned between two concentric circles with dissimilar radii. By selecting the inversion centre as one of the limiting points, any two circles may be made concentric via inversion.
Create a circle with a centre of 3 cm.
Once more, draw a circle with the same centre and a 2 cm radius.
Mark a point T 6 cm away from point O and connect it to OT.
Find the middle of OT and, using M as the centre, draw a circle with a radius of OM.
At P,Q and R,S, this circle intersects the two preceding circles. Connect point T to P, Q, R, and S.
The tangent to a circle with a radius of 2 cm is PT, QT. The tangent to a circle with a radius of 3 cm is RT, ST.
