👉 Learn how to solve for an unknown variable using parallel lines and a transversal theorems. Two lines are said to be parallel when they have the same slope and are drawn straight to each other such ...

Lines which are parallel have the same gradient. For example, \(\text{y = 2x + 1}\) and \(\text{y = 2x - 2}\) will be parallel because they both have a gradient of 2. We want to determine if the lines ...
