Points A, B, C, and D lie on circle M. Line segment BD is a diameter. The measure of arc CD equals the measure of arc DA. Circle M is shown. Line segment B D is a diameter. LIne segments E M and A M are radii. Lines are drawn from points C and A to point D to form chords. A line is also drawn from point C to point A. Angle C M A is 90 degrees. Arcs C B and B A are congruent.

What is the measure of angle ADM?

22.5°
30.0°
45.0°
67.5°

Which of the following contains a variable?

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
