This hands-on video walks you through each construction step by step, making it easy to follow along as you watch. More than just drawing, it builds the intuition behind each angle so you truly grasp the “why” behind the method.

Starting with a rough sketch, we identify the best side to use as the base—typically one of the given adjacent sides—to simplify angle placement. Step by step, we draw the base, construct the given angles at the correct vertices, and use arcs to mark the remaining points based on the side lengths. With careful alignment and compass work, we connect all vertices to complete the quadrilateral accurately. Courses on Khan Academy are always 100% free.
