Problem Analysis

We are given that angle AOB is equal to 138 degrees. Through points A and B, lines are drawn parallel to the sides of the given angle and intersect at point C. We need to find the angles formed at the intersection of these lines.

Solution

To find the angles formed at the intersection of the lines, we can use the properties of parallel lines and transversals. When a transversal intersects two parallel lines, the corresponding angles are congruent.

Let's label the angles as follows: - Angle AOC = x - Angle BOC = y

Since lines AB and OC are parallel, we can conclude that: - Angle AOC is congruent to angle AOB (given) - Angle BOC is congruent to angle AOB (corresponding angles)

Therefore, we have: - Angle AOC = 138 degrees - Angle BOC = 138 degrees

So, the angles formed at the intersection of the lines are both 138 degrees.

Answer

The angles formed at the intersection of the lines are both 138 degrees.
