# Construction Of Two Circles That Tangent Themselves and 2 Given Lines

| View Cart ⇗ | Info

An illustration showing how to construct two circles that tangent themselves and two given lines. “Draw the center line AB between the given lines; assume D to be the tangenting point of the circles; draw DC at right angles to AB. With C as center and CD as radius, draw the circle EDF. From E, draw Em at right angles to EF; and from F draw Fm at right angles to FE; then m and n are the centers for the required circles.”
