Vertices of a Polygon
Vertices of a Polygon is a skill on Pengi from Lesson 11: Investigation 1: The Coordinate Plane in Saxon Math, Course 3.
Key Concepts
Property A vertex (plural: vertices ) of a polygon is a point where two sides meet.
Examples A triangle with vertices at $(1, 1)$, $(4, 1)$, and $(1, 5)$ forms a right triangle. A square can have its vertices (corners) at $(0, 0)$, $(3, 0)$, $(3, 3)$, and $(0, 3)$. The vertices of rectangle $ABCD$ can be located at $A(2, 2)$, $B(2, 1)$, $C( 1, 1)$, and $D( 1, 2)$.
Explanation Think of vertices as the corners of a shape on the coordinate plane. If you're playing dot to dot, the vertices are the specific points you connect to draw your polygon. Each vertex has its own $(x, y)$ address, which defines the shape's exact position and size on the map.
