The figure shows a model of a roof truss. Based on the markings, which triangles are congruent? State the reason. Question 1 options: A) CDE, CDG; Reason: ASA B) CDA, CDB; Reason: SSS C) AFE, DFE, DHG, BHG; Reason: HL D) None of the triangles can be determined to be congruent based on the markings.

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
