href=\"https:\/\/www.splashlearn.com\/math-vocabulary\/geometry\/perimeter\">perimeter<\/a> of a plane figure is the total length of its boundary, It is the sum of its side-lengths. The <a href=\"https:\/\/www.splashlearn.com\/math-vocabulary\/geometry\/area\">area<\/a> of a closed plane figure is the measure of the space it occupies within its boundary. It is measured in square units.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Property of Symmetry<\/strong>: Some plane figures exhibit symmetry; they can be divided into two equal halves that are mirror images of each other.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Types<\/strong>: Plane figures can be classified into various types, including triangles, quadrilaterals, polygons, circles, and more.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Diagonals<\/strong>: Diagonals are line segments that connect non-adjacent vertices within certain plane figures, like polygons.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Regular and Irregular Plane Figures<\/strong>: Plane figures can be regular if all their sides and angles are equal.
