I demonstrated for Jaydn how angles of triangles and quadrilaterals can be determined if the figures include one or two tangent lines to circles. Due to the perpendicular relationship between a radius line and a tangent to the circle, a 90 degree angle can be shown to be at least one of the angles. I also showed her how segment lengths of tangent lines to a circle from external points are equal. We worked on several problems requiring the angles and segment lengths. There was no assignment.
