1. After a reflection across the x-axis, the image is the same size as the preimage. All angles and side lengths are the same. T/F 2. After a translation on the coordinate plane, the image faces the same direction as the preimage. T/F 3. If a preimage is rotated, the leg lengths and angle measures will change. T/F 4. Reflect triangle ABC over the y-axis, and then across the x-axis.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
