A carpenter is creating a woodwork pattern and wants two long pieces to be parallel. m 1= (8x + 20)° and m 2 = (2x + 10)°. If. x = 15, show that pieces A and B are parallel. Example 4 Continued. A line through the center of the horizontal piece forms a transversal to pieces A and B. 1 and 2 are same-side interior angles.

Given: In a plane, a y, b x, a 6 y, and y 6 z. Prove: x 6 z. Proof: Because 1. a y and a 6 b, line y is perpendicular to line b by Theorem 2. 3-11. Lines x and y are both perpendicular to line b, so. 3. x n y because two lines perpendicular to the same line are 4. parallel. Therefore, x 6 z because two lines that are.
