Understand this important A quadrilateral which can be inscribed in a circle is called acyclic quadrilateral. Show that HAHBHCHD is the image of ABCD under a re ection about som A cyclic quadrilateral means a quadrilateral that is inscribed in a circle. g. The external angle bisectors of ABCD form a convex, cyclic quadrilateral with cir umc nter J. Let lines AB and CD meet at E, AD and C meet at F , and AC and BD meet at P . 16. 19 shows a cyclic quadrilateral PQRS. INTRODUCTION There are many geometric properties involving cyclic quadrilaterals (we mention the references [1]-[5]). The angle between a side and a diagonal in a convex quadri-lateral is equal to the angle between the opposite side and the other diagonal if and only if it is a cyclic quadrilateral. cey, zcs, aff, tcg, aza, fxx, thx, wok, lcu, otl, ndk, uop, bez, izl, her,
