On Monday the average temperature is 15°C in Prague. The weather forecast shows a drop in temperature by 2°C by the next day.

By the end of the week the temperature is expected to drop even further by 4°C.

What is the temperature, in °C , in Prague at the end of the week?

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
