Storyboard Text

• My friend needed help on identifying the segment combinations on segments and arcs of circles so I decided to help her
• Then i told her that a secant is a line that intersects a circle in exactly two points and that the angles vertex outside the circle was determined as a tangent-secant
• tangent-secant
• And that when two secants intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.
• secant-secant
• If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.
• chord-chord
• And lastly I explained that a secant-secant was an angle whose vertex is outside a circle and whose sides are determined by two tangents.
• tangent-tangent
• "Thank you for explaining the segment combinations I understnad it now"
