Mathematics

ValentinkaMS [17]3 years ago
3 0

Answer:

The vertices of image are A'(0,0), B'(-1,-5) and C'(4,-5). The graph of image and preimage is shown below.

Step-by-step explanation:

From the given figure it is noticed that the vertices of  triangle ABC are A(0,0), B(1,5) and C(-4,5).

If a figure rotated at 180º about the origin, then

P(x,y)\rightarrow P'(-x,-y)

The vertices of image are

A(0,0)\rightarrow A'(0,0)

B(1,5)\rightarrow B'(-1,-5)

C(-4,5)\rightarrow C'(4,-5)

Therefore the vertices of image are A'(0,0), B'(-1,-5) and C'(4,-5).

The graph of image and preimage is shown below.
