Two adjacent (contiguous) angles, which together form a developed angle, are equal to 180 °. Since one angle is known and equal to 102 °, then the adjacent one will be equal to 180 ° – 102 ° = 78 °. Thus, when two straight lines intersect, four angles are formed that are equal in pairs.
Answer: 102 °, 102 °, 78 °, 78 °
