Oct 24, 2023 · A polygon is a closed, two-dimensional shape formed by straight line segments. The point where two segments meet is called a vertex, and the segments themselves are the sides. Classifying by Number of Sides: riangle (3 sides) Quadrilateral (4 sides) Pentagon (5 sides) Hexagon (6 sides) … and so on. Classifying by Side Length:

So, what is a polygon? A polygon is a closed sided figure, formed by three or more segments that never cross. And we can further identify it’s type as either convex, concave or regular. A convex polygon is when no line that contains a side of the polygon includes a point in the interior of the polygon. And a concave polygonis one that is not convex...
But how do we name a polygon? Polygons are named by the number of sides they have! And just like there are some incredible properties about triangles, there are some important theorems and properties regarding quadrilaterals. As in a triangle, quadrilaterals have both interior and exterior angles, and the sum of the interior angles in any quadrilat...

The Square. the little squares in each corner mean "right angle". A square has equal sides (marked "s") and every angle is a right angle (90°) Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).
These two quadrilaterals also share 2 pairs of parallel lines and 4 equal lengths. You can classify and compare shapes by using a Venn diagram. Each shape has been placed in the section of the ...
Classifying Polygons. Closed shapes or figures in a plane with three or more sides are called polygons. Alternatively, a polygon can be defined as a closed planar figure that is the union of a finite number of line segments. In this definition, you consider closed as an undefined term. The term polygon is derived from a Greek word meaning ...

In second grade, students are taking classifying 2D shapes one step further, recognizing and drawing shapes with specific attributes, including triangles, quadrilaterals, pentagons, and hexagons. At this stage, they begin to realize that shapes can fit into multiple categories. For example, they are already familiar with shapes like squares and ...
