Question

How many corners does this shape have?

A.6
B.10
C.12
D.13

Answer 1

Hint: The number of corners can be known by counting the number of sides or vertices. Here the number of sides or edges is equal to the number of corners.

Complete step-by-step answer:
The given figure is-

We have to find the number of corners in this figure. Corners are also called vertices. It is the point where two lines or edges meet. It is a polygon with $12$ edges. Edges are lines joining two points to form a shape. So first label the corners as numbers $1,2,3,...$ and count the corners as shown in the diagram below-

We can also name the corners as A,B,C,D,E,F,G,H,I,G,K,L and then count the number of alphabets. From the figure it is clear that there are $12$ corners of this figure.
Hence the correct answer is ‘C’.

Note: We can also find the number of corners by counting the edges as the number of edges is equal to the number of corners for this figure. There is also a formula given to count the number of faces, edges or vertices of a figure which is-
$ \Rightarrow $ Faces + Vertices=$2$+Edges
Using this formula we can count the vertices, edges, or faces of a cube, cuboid or cylinder.
