Triangle abc is rotated to create the image a'b'c'. which rule describes the transformation?

 (x,y) → (-x,-y)

Step-by-step explanation:

In geometry , a rotation is an transformation of a shape by rotating it with a certain number of degree about a particular point which is called the center of rotation , and is represented by ,where x is the angle of rotation about a center point o.

Now  consider the preimage of triangle ABC be (x,y) and for angle of rotation for rotating triangle ABC to A'B'C' is  180° or -180° about center of rotation(0,0).

i.e.

the image formed is (-x,-y).

In figure we can see the image of triangle ABC( In first quadrant ) is triangle A'B'C in third quadrant with center of rotation origin (0,0).

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
