WebAngles that are in the area between the parallel lines like angle H and C above are called interior angles whereas the angles that are on the outside of the two parallel lines like D and G are called exterior angles. Angles that are on the opposite sides of the transversal are called alternate angles e.g. H and B. WebSep 4, 2024 · If the interior angles of two lines on the same side of the transversal are supplementary then the lines must be parallel. Example 1.4.3 Find x and the marked angles: Solution The lines are parallel so by Theorem 1.4.3 the two labelled angles must be supplementary. x + 2x + 30 = 180 3x + 30 = 180 3x = 180 − 30 3x = 150 x = 50 ∠CHG = x = … brown kerf style replacement door bottom
