Now you will use GeoGebra to explore the trigonometric ratios as the acute angle changes in a right triangle. Return to trigonometric ratios. Move point D until the Show Side Ratios box appears, check the box, and complete each step below. Part A
Move point F to various positions so the measure of ∠A is approximately 15°, 30°, 45°, 60°, and 75°, and record the ratios of the sides of ΔABC and ΔADE.

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
