SECANTS

1
SECANTS

• Secant
• - A line that intersects the circle at two points.

2
2 Secants On (Inscribed Angle)

• The angled formed is half the intercepted arc.

3
Two Secants - In

• If two secants intersect inside the circle, then
  the measure of the angle formed is 1/2 the sum of
  the measures of the arcs intercepted by the angle
  and its vertical angle.

4
Secant/Tangent - On

• If a secant and a tangent intersect at the point
  of tangency, then the measure of each angle
  formed is 1/2 the measure of the intercepted arc.

5
Secant/Tangent, 2 Secants or 2 Tangents - Outside

• If a secant and a tangent, two secants or two
  tangents intersect outside the circle, then the
  measure of the angle formed is 1/2 the positive
  difference of the measures of the intercepted
  arcs.
