Geometry Applications : EXAMPLE: Ifquadfi1atera1PLAY has angles P: 59 degrees L: 37 degrees A: 143 degrees Y: 121 degrees Which sides are parallel? Sketch the figure.Parallel lines are seen in many common 2D shapes. For example, Each side of a square is made of a line segment that is part of a line. The opposite sides of a square are parallel. There are also many examples of parallel lines in real life. For example, The lines that pass by the sides of a table top are parallel.of two parallel lines, then it is perpendicular to the other line. If h k and j ⊥ h, then j ⊥ k. Proof Example 2, p. 150; Question 2, p. 150 Theorem 3.12 Lines Perpendicular to a Transversal Theorem In a plane, if two lines are perpendicular to the same line, then they are parallel to each other.
