4. Vertex A of triangle ABC is located at the
point (2,5). Which transformation moves
vertex A to the point (-2,5)?

A reflection across the x-axis
B reflection across the y-axis
© (x, y) → (x+4, y)
D (x, y) - (x - 4, -y)

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
