One of the angles formed at the intersection of two straight lines AB and CD at the point M is 68 degrees, find the remaining angles.

One of the angles formed at the intersection of two straight lines AB and СD at the point M is 68 degrees, find the remaining angles.

1) What is the degree measure of the angle adjacent to the angle, the degree measure of which is 68?

180 – 68 = 112.

2) What is the degree measure of the remaining angles?

Since when two straight lines AB and CD intersect at point M, two pairs of vertical angles are formed, and as you know, the vertical angles are equal, then the degree measures of the remaining angles will be equal to 68 and 112.

Answer: the degree measures of the required angles are 112, 112 and 68.
