The sum of the measures of the angles of the parallelogram is 360 degrees. in the parallelogram angles a and d have the same measure as well as angles c and b. if the measure of angle c is four times the measure of angle a find the measure of each angle

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
