Question 1 of 6
1. Question
Find the number of vertices and edges.
-
Vertices`=` (2)Edges`=` (4)
Hint
Help VideoCorrect
Great Work!
Incorrect
A vertex is a point or node that is connected within a network.An edge is a line that connects one or more vertices in a network.First, count the vertices that are marked as points in the image.
There are `2` points. Therefore, this shape has `2` vertices.Next, find the number of edges by counting the lines with both ends connected by vertices.
Notice that the circle on the right starts from a vertex and goes around back to the same vertex. That still counts as an edge.There are `4` lines with both ends connected to vertices. Therefore, this shape has `4` edges.Vertices`=2`Edges`=4` -

Good job!
Incorrect
A vertex is a point or node that is connected within a network.An edge is a line that connects one or more vertices in a network.First, count the vertices that are marked as points in the image.
There are `5` points. Therefore, this shape has `5` vertices.Next, find the number of edges by counting the lines with both ends connected by vertices.
There are `6` lines with both ends connected to vertices. Therefore, this shape has `6` edges.Vertices`=5`Edges`=6` -
