DILATION
Contraction :3/4, 1/5 . .......As a dilation with a scale factor ofless than 1, . butgreater than 0 isContraction
Expansion :1.XX, X ; XXX -X............ As a XXXXXXXX with a XXXXX XXXXXXXXXXXXX
XXXX X is XXXXXXXXX.
**( -2 is-XX expansion opposite XXXXXXXXX XX the center XX XXXXXXXX XXXX 180X XXXXXXXX)
XXXXX factor XX XXX dilation = Image/XXX-image
XXXXX XXXXXX XX the dilation= M’X’/ XX = 4/10 =0.X
The XXXXXXXXXXX XX the XXXXX XXXXXXXX are A(X,0), B(0, -6),C(X,0)
XXXXX factor k = X/X, and XXXXXX XX XXXXXXXX = (X,X) or XXXXXX.
The coordinates of image after XXXXXXXX of XXXXXXXXXXX (x,y) XXXXXXX (kx,XX)
So, after XXX XXXXXXXX XXX coodrinates XX the XXXXX will XX :
(X*1/2,0*X/2), (X*1/X, -X*1/2), (X*X/2,0*1/2)
=(X,X),(0, -X),(X,0)
XXXX XXX XXXXX is placed in XXXopposite XXXX of the XXXXXX XX XXXXXXXX X and XXXX with a 180X rotation.
So, the scale factor XXXX beXXXX than 0 XXX has a–XX sign.
Thus XXX XXXXX XXXXXX of XXX XXXXXXXX = - (R’S’/XX) = - (XXXX/XXX) =-4.
The XXXXXXXXXXX XX the XXXXX triangle XXX (-4,1), (-X,-X), (-X,-2)
XXXXX factor X = -2 and XXXXXX of XXXXXXXX (0,0)or origin.
XXX XXXXXXXXXXX of image XXXXX dilation XX XXXXXXXXXXX (x,y) XXXXXXX (XX,ky)
After the dilation XXX XXXXXXXXXXX XX XXX XXXXX XXXX be :
(-4*-2, X*-X), (-X*-X, -4*-X), (-2*-X, -X*-X)
=(8, -2),(6,X), (X,4)
*(It is XXXX XX XXXXXXXX expansion or XXXXXXXX dilation)
