It is proved that their number is at most 4. The result is generalized for spherical and hyperbolic geometries. This contrasts with Poncelet type porisms where usually infinitude of such polygons is proved, provided that one such polygon already exists.<\/p>\n      <p>An inequality involving ratio of lengths of line segments is used. Alternative way of using Maclaurin\u2013Braikenridge's conic generation method generalized by Brianchon is also discussed. Properties related to constructibility with straightedge and compass are also studied. A new proof, based on mathematical induction, of generalized Maclaurin\u2013Braikenridge's theorem is given. We also gave examples of regular polygons for which number 4 is realized.<\/p>\n    <\/div>\n  <\/div> -->\n\n  <!-- Footer -->\n  <div class=\"ann-footer\">\n    <span>Mathematics Research Center \u00b7 ASOIU, Baku<\/span>\n    <a href=\"\/seminars\/\">All seminars \u2192<\/a>\n  <\/div>\n\n<\/div><!-- \/.ann-block -->\n<!-- \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\n     END SEMINAR ANNOUNCEMENT\n     \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 -->\n\n\n<!-- \u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\n     BLANK TEMPLATE \u2014 copy this for new announcements\n     \u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500 -->\n<!--\n\n<div class=\"ann-block\" data-type=\"general\">\n\n  <div class=\"ann-topbar\"><\/div>\n\n  <div class=\"ann-logo-row\">\n    <img decoding=\"async\" class=\"ann-logo\" src=\"LOGO_URL_HERE\" alt=\"ASOIU Mathematics Research Center\">\n  <\/div>\n\n  <div class=\"ann-poster\">\n    <div class=\"ann-type\">General Seminar<\/div>\n    <div class=\"ann-poster-rule\"><\/div>\n    <div class=\"ann-title\">\n      TALK TITLE HERE\n    <\/div>\n    <div class=\"ann-speaker\">Speaker Name<\/div>\n    <div class=\"ann-affil\">Institution<\/div>\n  <\/div>\n\n  <div class=\"ann-meta\">\n    <div class=\"ann-meta-item\">\n      <svg viewBox=\"0 0 16 16\" fill=\"currentColor\"><path d=\"M7 0H2a1 1 0 00-1 1v2h14V1a1 1 0 00-1-1H7zm7 4H1v10a1 1 0 001 1h12a1 1 0 001-1V4z\"\/><\/svg>\n      <span><span class=\"ann-meta-label\">Date&nbsp;<\/span>Month DD, YYYY<\/span>\n    <\/div>\n    <div class=\"ann-meta-item\">\n      <svg viewBox=\"0 0 16 16\" fill=\"currentColor\"><path d=\"M8 1a5 5 0 100 10A5 5 0 008 1zM0 8a8 8 0 1116 0A8 8 0 010 8z\"\/><path d=\"M7.5 4.5v4l2.5 1.5.5-.87L8.5 8V4.5z\"\/><\/svg>\n      <span><span class=\"ann-meta-label\">Time&nbsp;<\/span>HH:MM<\/span>\n    <\/div>\n    <div class=\"ann-meta-item\">\n      <svg viewBox=\"0 0 16 16\" fill=\"currentColor\"><path d=\"M8 0C5.24 0 3 2.24 3 5c0 3.75 5 11 5 11s5-7.25 5-11c0-2.76-2.24-5-5-5zm0 7.5a2.5 2.5 0 110-5 2.5 2.5 0 010 5z\"\/><\/svg>\n      <span><span class=\"ann-meta-label\">Location&nbsp;<\/span>Room \/ Online<\/span>\n    <\/div>\n  <\/div>\n\n  <div class=\"ann-abstract\">\n    <div class=\"ann-abstract-label\">Abstract<\/div>\n    <div class=\"ann-abstract-body\">\n      <p>Abstract text here.
