1. Construct a quadrilateral ABCD, given that angleA = 60°, AB = 2.8 cm, BC = 3 cm, CD = 2.5 cm and DA=3.2 cm

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

step-by-step explanation:

he answer is x=1x3 because x=1 to x=3
