When two straight lines intersect, four corners are formed (1, 2, 3, 4). Angles 1 and 2, 2 and 3, 3 and 4, 4 and 1 are adjacent angles and the sum of the two angles is 180 degrees. Angles 1 and 3, 2 and 4 are vertical angles and such angles are equal to each other. Suppose that angle 1 is equal to 118 degrees, then the adjacent angle 2 will be equal to 180 – 118 = 62 degrees, and the vertical angle 3 to it will be equal to it, that is, 118 degrees. Vertical angle 2 is angle 4 equal to 62 degrees.
Answer: The angles are equal: 118, 118, 62, 62 degrees.
