Quadrantal angles (0, 90, 180, and 270 degrees), and the values of the sine, cosine, and tangent of each of these angles. From the trig lessons in the Algebra 2 course by Derek Owens.
Simple quadrilaterals are either convex or concave. The interior angles of a simple (and planar) quadrilateral ABCD add up to 360 degrees of arc, that is. This is a special case of the n-gon interior angle sum formula (n â 2) Ã 180Â°. All convex quadrilaterals tile the plane by repeated rotation around the midpoints of their edges.
