A logo is 15 centimeters wide. If the logo is to be dilated by a factor of 7/4, find the width of the logo.
15(7/4) = 13/4
15(7/4) = 26/4
15(7/4) = 26 1/4
15(7/4) = 1 3/4
The triangle ABC has vertices A(-4, 1); B(-1, 1); C(-1, 3) as shown. Reflect triangle ABC twice, first across the y-axis, then across the x-axis. Then rotate triangle ABC 180o about the origin. What do you notice about the two transformations? Make a conjecture.
The rotation got the imagen where the preimage was first.
Both reflections moved the oreimage as 180o would have.
Both transformations return the preimage to its original position.
Nothing change, each one canceled the other.
