  1. 12.4 Angle Measure & Segment Lengths

  2. 12.4 – Angle Meas. & Segment Lgth. • A secant is a line that intersects a circle at 2 points

  3. 12.4 – Angle Meas. & Segment Lgth. • Angles formed by secants, tangents, and chords intercept arcs on circles. The measures of the intercepted arcs can help you find the measures of the angles.

  4. 1 2 x° y° 12.4 – Angle Meas. & Segment Lgth. • The measure of an angle formed by 2 lines that intersect INSIDE a circle = (x + y)

  5. (x – y) 1 2 y° x° 12.4 – Angle Meas. & Segment Lgth. • The measure of an angle formed by 2 lines that intersect OUTSIDE a circle =

  6. 95° x° 90° 46° 20° x° 12.4 – Angle Meas. & Segment Lgth. • Find x for each example

  7. x° 110° 30° x° 110° 70° 12.4 – Angle Meas. & Segment Lgth. • Find x for each example

  8. a c b d a * b = c * d (w + x)w = (y + z)y 12.4 – Angle Meas. & Segment Lgth. • Finding Segment Lengths inside or outside a circle x w y z
