Write the following biconditional as two conditional statements:

Two angles are complementary if and only if the sum of their measures is 90.

Step-by-step explanation:

two angles that equal 90 degrees are complemterary

two complementerary angles equal 90 degrees

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
