Sides are the straight lines that form a shape. While Nico continues to play the Shape Mayhem game, let's review! Remember, a 2D shape almost always has sides and vertices. A circle will never have any sides or vertices. One of them is this shape, which is a circle! What do you notice about the sides and vertices of this circle? There are zero sides and zero vertices. Some shapes are an exception to the rule that all 2D shapes have sides and vertices. How many sides and vertices does a pentagon have? There are five sides and five vertices! A pentagon always has five sides and five vertices. You might notice there are different shapes that share the same number of sides and vertices. A trapezoid always has four sides and four vertices, which also makes it a part of the quadrilateral family. How many vertices does it have? There are four vertices. How many sides does it have? There are four sides. A quadrilateral, like this square, always has four sides and four vertices! Now we have learned about sides and vertices, let's look at some different shapes. Knowing the number of sides and vertices a shape has can help you to identify shapes, or classify them into shape families! For example, this square has four sides and four vertices. If we talk about more than one corner, we call them vertices. If we talk about one corner, we call it a vertex. Vertices are the corners where two straight lines meet, like all of these corners here. What are sides and vertices? Sides are the straight lines that form a shape, like all of these sides here. A 2D shape is a flat closed shape that almost always has sides and vertices. To help Nico play the game, let's learn about sides and vertices of 2D shapes. I wonder?" It looks like a game has started on the console! However, Nico needs to learn about sides and vertices of 2D shapes to play the game. Nico has found an old game console in the attic. The table below shows an overview of shapes, their number of sides and their vertices. How many sides and vertices does a triangle have? Triangles have three sides and three vertices, hence the name tri (= three). In this text we learned that squares and trapezoids have four sides and four vertices, whereas a pentagon has five each. A vertice, or vertex, is where two sides meet to form a corner. A side is a straight line that makes up a closed 2D shape. You can use these to help identify 2D shapes. Sides and Vertices of 2D Shapes – Summary How many sides and vertices does a circle have? A circle is a special case, because it has 0 sides and 0 vertices, so when someone asks you what shape has 0 sides and 0 vertices, you can tell them a circle! How many sides and vertices does a pentagon have? A pentagon is a shape with 5 sides and 5 vertices, so when someone asks you what shape has 5 sides and 5 vertices, you can tell them pentagons do! How many sides and vertices does a quadrilateral have? Quadrilaterals have 4 sides and 4 vertices, so when someone asks you what shape has 4 sides and 4 vertices, you can tell them all quadrilaterals do! Therefore, a square and trapezoid are examples of a shape with 4 sides and 4 vertices. Squares and trapezoids are a type of quadrilateral. Sides and Vertices on Squares and Trapezoids A side is a straight line that makes up a closed 2D shape.Ī vertice, or vertex when we are talking about just one, is where two sides meet to form a corner. So what are sides and vertices? Let’s find out all there is to know about sides and vertices in this text. Sides and Vertices of 2D Shapes – Summary.Sides and Vertices on Squares and Trapezoids.
