Situation 43: Can You Circumscribe a Circle about this Polygon?
... Also, no parallelograms other than rectangles are cyclic. Moreover, every isosceles trapezoid is cyclic. [Note: A commonly used definition of trapezoid is that it is a quadrilateral with exactly one pair of parallel sides. However, trapezoids are defined by some sources as a quadrilateral with at le ...

... an orientation on such angles by designating the positive -axis ray as the initial ray and the other ray as the terminal ray. (What does it mean if these rays coincide?) Thus we adopt a dynamic viewpoint: the measure of this angle is determined by how we move from the initial ray to the terminal ray ...

... In this problem, you need to find the angle measures of two alternate interior angles given an exterior angle. Use what you know. There is one angle that measures 80◦ . Angle β corresponds to the 80◦ angle. So by the Corresponding Angles Postulate, m6 β = 80◦ . Now, because 6 α is made by the same i ...

I would first have the students draw a line that is 5 inches long, then I would have them draw another line from the same endpoint that is 4 inches long. Finally I would have them connect their lines to make a tri ...
