DOUBLE POINTS!!!!!!!
ROTATE POINT (-9.946, 0) BY 90 DEGREES CLOCKWISE
(0, 9.946)
IF I ROTATE POINT (0,0) BY 180 DEGREES THEN DILATE BY A SCALE FACTOR OF (1-0.08+0.09-0.01-1), WHAT DO I GET?
(0,0)
REFLECT POINT (9,2) OVER THE X-AXIS.
(9,-2)
DILATE POINT (9,9) BY A SCALE FACTOR OF 1/2.
(4.5,4.5)
TRANSLATE POINT (0,0) DOWN 8
(0,-8)
DOUBLE POINTS!!!!!
DILATE POINT (-990293493.992940394,0) BY 0, THEN ROTATE -180 DEGREES, WHAT DO YOU GET?
(0,0)
IF I ROTATE POINT (7,180) 180 DEGREES, THEN ROTATED IT 90 DEGREES CLOCKWISE, WHAT WOULD I GET?
(-180,7)
REFLECT POINT (8,30) OVER THE Y-AXIS.
(-8,30)
DILATE POINT (8,5) BY A SCALE FACTOR OF 2.
(16,10)
TRANSLATE POINT (1,9) UP 3
ROTATE POINT (-9, 9) BY 90 DEGREES COUNTERCLOCKWISE.
(-9,-9)
IF I ROTATE POINT (9,9) 180 DEGREES, THEN REFLECT IT OVER THE X-AXIS, WHAT DO I GET?
(-9,9)
REFLECT POINT (-99,200.2) OVER THE Y = X.
(-200.2,-99)
DOUBLE POINTS!!!!!!!!
DILATE POINT (1/9,99) BY A SCALE FACTOR OF 1/3.
(1/27,33)
DOUBLE!!! TRANSLATE POINT (1,1) LEFT 8
(-7,1)
ROTATE POINT (1,1) 90 DEGREES CLOCKWISE.
(1,-1)
DOUBLE POINTS!!!!!!
IF I STARTED WITH (3, 4) THEN ROTATED X DEGREES, AND AFTER DILATING BY A SCALE FACTOR OF 1.5 ENDED UP WITH (-6, 4.5), HOW MUCH DID I ROTATE BY?
90 CLOCKWISE, OR 270 COUNTERCLOCKWISE
WHAT HAPPENS TO THE X AND Y COORDINATES WHEN YOU REFLECT OVER THE ORIGIN?
THEY BOTH CHANGE SIGNS.
IF YOU DILATE BY A FACTOR OF 2, DOES THE X COORDINATE INCREASE IN VALUE OR DECREASE WHILE IN THE 2ND QUADRANT?
IT WILL DECREASE
WHAT HAPPENS TO THE Y COORDINATE WHEN YOU TRANSLATE BY A SCALE FACTOR OF (3,-5)
IT GOES DOWN 5
ROTATE POINT (3,2) 270 DEGREES COUNTER CLOCKWISE AND THEN ROTATE -180 DEGREES.
(-2, 3)
IF YOU REFLECT COORDINATE (3,2) OVER THE X-AXIS, THEN ROTATE IT 180 DEGREES, WHAT ARE THE NEW COORDINATES?
(-3,2)
