Convex & Concave Quadrilaterals | Overview, Examples & Attributes from Chapter 16/ Lesson 14 132K Learn what concave and convex quadrilaterals are. See the properties of convex and concave quadrilaterals and find examples of each, such as concave trapezoids. ...
Using tools of parallel projective transformation and analytic geometry, we derived several theorems including the proof of the existence of circumscribed ellipses of convex quadrilaterals, the properties of its minimal coverage area, and locus center, respectively. This simple approach lays a solid ...
