Worksheet Template Unit 5 Homework Packet Parallel Lines Perp from Parallel Lines And Transversals Worksheet Answers , source: 2100 Evaluate the angles x and y shown, giving rea- sons for your answers. When a line intersects two or more lines the angles formed at the intersection points create special angle pairs. \begin{aligned}(24\times24^{11}) &-  (15\times15^9) \\ (3\times8\times24^{11}) &- (3\times5\times15^9)\end{aligned}, (3\times8\times24^{11}) - (3\times5\times15^9) = 3([8\times24^{11}] - [5\times15^9]). Example: Prove that the sum of the interior angles of a triangle add up to 180\degree, Here we can see a triangle with the angles \textcolor{red}{a}, \textcolor{limegreen}{b} and \textcolor{blue}{c}, \textcolor{limegreen}{b} = \textcolor{black}{y} (Corresponding angle), \textcolor{red}{a} = \textcolor{black}{x} (Alternate angles), \textcolor{blue}{c} + \textcolor{black}{x} + \textcolor{black}{y} = 180\degree, \textcolor{red}{a} + \textcolor{limegreen}{b} + \textcolor{blue}{c} = 180\degree, So in these four lines we have proved the angles in a triangle add up to 180\degree. For any 3 consecutive even numbers: 2n, (2n+2) and (2n+4), adding them together gives us, Now, to show that this number is divisible by 6 we simply take out a factor of 6, then we get.
