Lines AB and CD intersect at point o, the degree measures of the angle AOC is 56 degrees.

Lines AB and CD intersect at point o, the degree measures of the angle AOC is 56 degrees. Find the degree measures of the angles DOB and AOD.

When two straight lines intersect, four corners are formed. At the intersection of straight lines AB and CD, angles AOC, DOB are formed, which are vertical and such angles are equal to each other, that is, the angle AOC = DOB = 56 degrees. The AOD angle is an adjacent angle to the AOC angle, and these angles add up to 180 degrees, so the AOD angle is 180-56 = 124 degrees.
Answer: The angle DОВ, formed at the intersection of two straight lines is fifty-six degrees, and the angle AOD, formed at the intersection of the same straight lines is 124 degrees.
