Question 1

chord chord angles

Answer 1

Formed by two chords that intersect inside(but not at the center of) a circle; equal to half the sum of the arcs intercepted by the Chord-Chord angle and its vertical angle

theta= m arc a+m arc b/2

Question 2

Secant-Secant Angle
Tangent-Tangent Angle:
Secant-Tangent Angle

Answer 2

Equal to half the difference of larger arc minus smaller arc (arc1-arc2/2)

Question 3

theorem 1

Answer 3

If two inscribed or tangent-chord angle intercept the same or congruent arc(s) then they are congruent

Question 4

theorem 2

Answer 4

the sum of the measures of a tangent-tangent angle and it’s minor arc is 180*

Question 5

theorem3

Answer 5

If a quadrilateral is inscribed in a circle then its opposite angles are supplementary

Question 6

SecaANT SECANT PT

Answer 6

If a quadrilateral is inscribed in a circle then its opposite angles are supplementary

Question 7

Tangent secant pt

Answer 7

If a tangent segment and a secant segment are drawn from an external point to the circle, then the square of the measure of the tangent secant is equal to the product of the measures of the entire secant segment and its external part

Question 8

tangent chord angles

Answer 8

Formed by a tangent and a chord; equal to half the measure of the intercepted arc
