Transformation Review

Triangle XYZ has vertices x(2,3), Y(5,6), and Z(8,6).  What rule can be used to find the new coordinates of point X, if the triangle is translated 6 units down and 4 units to the right?

• (x,y)⊣(x-4, y+6)
• (x,y)⊣(x-6, y+4)
• (x,y)⊣(x+6, y-4)
• (x,y)⊣(x+4, y-6)

When quadrilateral PRST is translated to create quadrilateral P'R'S'T', which statement is true?

• The side lengths of quadrilateral P'R'S'T' are twice the side lengths of quadrilateral PRST
• The side lenths of quadrilateral P'R'S'T' are of equal length to the side lengths of quadrilateral PRST
• The side lengths of quadrilateral P'R'S'T' are 9 units longer than side lengths of quadrilateral PRST
• The angle measures of quadrilateral P'R'S'T' are greater than the angle measures of quadrilateral PRST
