Step 1
This will form two right triangles, one in each circle. In circle P, the hypotenuse of the right triangle is the radius of the circle, which is 5. The other leg of the triangle is half the distance between the centers of the circles, which is 3. Using the Show more…

The common chord AB between ⊙ P and ⊙ Q is perpendicular to the segment connecting the centers of the circles. If AB=10, what is the length of PQ? Explain your reasoning.

Circles $P$ and $Q$ have radii 6 and 2 and are tangent to each other. Find the length of their common external tangent $\overline{A B}$ . (Hint: Draw $\overline{P Q}, \overline{P A},$ and $\overline{Q B}$ .)
