How do I solve this ?
eduard

Look at the picture.

ΔZYX and ΔDYC are similar. Therefore the lengths of sides are in proportion:

\dfrac{DC}{ZX}=\dfrac{DY}{ZY}

DC = x

ZX = 16

DY = a

ZY = a + a = 2a

Substitute:

\dfrac{x}{16}=\dfrac{a}{2a}

\dfrac{x}{16}=\dfrac{1}{2}       <em>multiply both sides by 16</em>

\boxed{x=8}

<h3>Answer: CD = 8</h3>

What could be the ordered pairs representing vertices C and D of quadrilateral abcd so that the new fire department is congruent
ohaa [14]
Given that <span>a city grid of Anytown, USA is shown on the grid below. The fire department is represented by quadrilateral RSTU. Another fire department is opening in a different part of the city to maximize fire protection. The size of the new department's property must be congruent to the older department. Vertices A and B are plotted on the grid to represent two vertices of the new fire department quadrilateral ABCD.

Map of Anytown; the line y equals 7 is Main Road; the line y equals 3 is Rose Lane; the line y equals negative 1 is Crystal Avenue; the line x equals negative 4 is Brick Street; the diagonal line is Dogwood Drive; Old Fire Department forms quadrilateral with ordered pairs R at negative 4, 7, S at negative 1, 7; T at negative 1, 3; U at negative 4, 3; A is at 4, negative 1 and B is at 1, negative 1

Recall that t</span><span>wo shapes are said to be congruent if the lengths of the sides and the angles are the same.

For quadrilateral RSTU to be congruent to quadrilateral ABCD, then RS = AB, RU = AD, ST = BC and TU = CD

Also, the figure ABCD is a result of a rigid body translation of the figure RSTU.

Given that R is at point (-4, 7) and A is at point (4, -1), also given that S is at point (-1, 7) and B is at point (1, -1).

It can be seen that points AB is a result of refrecting points RS across the y-axis and then shifting the resulting points down by 8 units.

Thus, given point T as (-1, 3) and point U as (-4, 3), refrection of points T and U across the y-axis will result in points (1, 3) and (4, 3), then shifting the resulting points down by 8 units will result to points (1, -5) and (4, -5)

Therefore, the ordered pairs representing vertices C and D of quadrilateral ABCD so that the new fire department is congruent to the old fire department are C(1, -5) and D(4, -5).</span>
