Q4 - Geo - Hw #02/03

How many common tangents can be drawn between the two circles?

Put the circles in order from LEAST (left) possible tangent lines to MOST (right) possible tangent lines

•

• 

The radius and any tangent line intersect at a right angle.

a

b

c

Right Angle

Radius

Tangent Line

What is true about these common tangents?

• RP = RS

• PT = TS

• ST = SR

• Common tangents are never congruent, the only appear congruent

Match the following

• Equidistant Chords

• 
• Congruent Chords

• 
• Tangent Circles

• 
• Common Tangents

• 

AD = ​ (a)  

XQ = ​ (b)  

BY = ​ (c)  

• BC
• QY
• YC
• AX
• XD

How long is CD?
