👉 Learn how to solve for an unknown measure using parallel sides. When two parallel lines are cut by a transversal, there are some congruents angles that are formed. Some of the congruents angles formed include the corresponding angle, alternate angle, etc. Also, when three parallel lines are cut by two transversals, there are some congruents and proportional sides that are formed. Using the knowledge of similar polygons enables us to solve for unknown measures formed by parallel lines. 👏SUBSCRIBE to my channel here: https://www.youtube.com/user/mrbrianmclogan?sub_confirmation=1 ❤️Support my channel by becoming a member: https://www.youtube.com/channel/UCQv3dpUXUWvDFQarHrS5P9A/join 🙋♂️Have questions?
