Monocular cues allow us to judge distance and depth whether we are viewing with one eye or two. For example, the image size of an object appears larger when it is close and smaller when it is far away. Parallel lines seem to come together as they mo...
This clip focuses on isosceles triangles, explaining that the equal sides are called the legs, while the remaining side is called the base. The clip notes that the base angles have the same measure, adding that, "

This clip revisits some of the essential points in the lesson on angles, arcs and sectors, including angle measurement and special angle relationships that occur when lines intersect. The clip also mentions angle measurement in circles, and explains...
This clip explains that several angles are created when a transversal intersects two parallel lines. The clip then defines alternate interior angles and corresponding angles.
Comparing two equations with the same slope but different y-intercepts.
Presented is a system of equations to which there is no solution the lines are parallel and a system of equations to which the solution is coincident lines the two equations share the same, infinite number of solutions.
