The radius of the a circle is: is a line segment with its endpoints on the circle.

is a line segment from the center of a circle to a point on the circle

is a chord that passes through the center of a circle. It is twice the length of a radius of that circle

is a part of a circle with all its points on the circle

is a line segment from the center of a circle to a point on the circle

Step-by-step explanation:

I think you can solve this question now

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
