50 ! abc is transformed to dbe a| |-- | \ | \ | \ | \ | - - - - - - - - -e | | | | | | | | (a) which rigid transformation can be used to map abc on to dbe? (b) what is true about the corresponding sides and angles of the image and the preimage? explain. (c) identify the corresponding sides and angles of the image and the preimage.

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
