CPM Homework Help : INT1 Problem 8-18

Use tracing paper and a series of rigid transformations to determine if these two polygons are congruent. If possible, find the lengths of $z$ and $y$ .

Quadrilateral, A, B, C, D, with side A, B = z, side C, B = 8.4, side D, C, = 6 and side D, A, = 3. Quadrilateral, W, X, Y, Z ,with side W, X, = 15, side X, Y, = 8.4, side Z, Y, = 6, side W, Z, = y.

Hint:

What two transformations are needed to move $ABCD$ onto $WXYZ$ ?

More Help:

To find $z$ and $y$ , divide or multiply by the zoom factor.

Partial Answer:

$y=3$
