There are several math topics that act as foundations for understanding ACT Math, even though there are not many questions specifically dedicated to the topic. This is most certainly the case for line and angle problems. Though it is rare to see a pure line and angle problem (without the addition of other geometric shapes), you’ll need to know just how lines and angles work and how to solve for all your missing measures before you can take on those more complex problems.
This will be your complete guide to lines and angles on the ACT—what they are, how you’ll see them on the test, and how to solve these types of questions to maximize your points on test day.
