Which object does not exhibit rotational symmetry?

The correct answer is image 3. Clock

Explanation:

An object exhibits rotational symmetry if it can be rotated and still look the same or coincide with the original object. For example, if you rotate a circle this will be symmetrical or will look the same at any rotation. According to this, the clock or third object does not exhibit rotational symmetry because due to details such as the clock hands or the bells if you rotate the image in any direction and at any degree, the image will not coincide with the original one, and therefore there is not symmetry when the object is rotated.

answer

point o.

step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
