In geometry, a vertex (plural: vertices) is a point where two or more line segments, lines, or rays meet to form an angle. In the context of 2D shapes, vertices are the corners or points where the sides of the shape meet. In 3D shapes, vertices are the points where the edges of the shape meet.

To identify the vertices of a shape, you can count the number of corners or points where the sides of the shape meet. For example, in a triangle, there are three vertices, and in a square, there are four vertices.

**Definition:**Understand that a vertex is a point where two or more line segments, lines, or rays meet to form an angle.**Identifying Vertices:**Learn how to identify the vertices of different shapes by counting the corners or points where the sides meet.**Examples:**Practice identifying and naming the vertices of various 2D and 3D shapes, such as triangles, squares, cubes, and more.**Properties:**Explore the properties of vertices in different shapes, such as the number of vertices in a polygon or the arrangement of vertices in a polyhedron.

Understanding vertices is essential for working with geometric shapes and understanding their properties. Practice identifying and visualizing vertices in different shapes to strengthen your grasp of this concept.

Algebra: Writing, interpreting, and using mathematical expressions and equations

Students write mathematical expressions and equations that correspond to given situations, they evaluate expressions, and they use expressions and formulas to solve problems. They understand that variables represent numbers whose exact values are not yet specified, and they use variables appropriately. Students understand that expressions in different forms can be equivalent, and they can rewrite an expression to represent a quantity in a different way (e.g., to make it more compact or to feature different information). Students know that the solutions of an equation are the values of the variables that make the equation true. They solve simple one-step equations by using number sense, properties of operations, and the idea of maintaining equality on both sides of an equation. They construct and analyze tables (e.g., to show quantities that are in equivalent ratios), and they use equations to describe simple relationships (such as 3x = y) shown in a table.
