If two angles are consecutive interior angles formed when a transversal cuts two parallel lines, then they are supplementary. You know that are consecutive interior angles. Using the Law of Detachment, which conclusion could you make?
.triangle ABC is inscribed in circle with centre O. seg AD is a diameter. tangent to the circle at point D intersects seg AB in X and AC in Y.
to prove: AB x AX = AC x AY.
circle P and circle Q are externally tangent .AB is common external tangent if the radius of the circle P and Q are 8cm And 12cm respectively .find the lenght of the tangent segments AB.
