Answer:
Complete the missing parts of the paragraph proof.
By the definition of
✔ supplementary
angles, the sum of the measures of angles 1 and 2 is 180 degrees. Likewise, the sum of the measures of angles
✔ 3 and 2
is 180 degrees. By the
✔ substitution
property, mAngle1 + mAngle2 = mAngle3 + mAngle2. Subtract the measure of angle
✔ 2
from each side. You get mAngle1 = mAngle3, or Angle1 Is-congruent-to Angle3, by the definition of congruence
