Chapter 9.1, Problem 5CYP

To determine

To find: The graph and angle is $\Delta BCD$ .

Answer to Problem 5CYP

The angle is $\Delta BCD$ above solution.

Explanation of Solution

Given information:

The given points is $B\left(-3,3\right)$ , $C\left(1,4\right)$ , and $D\left(-2,-4\right)$ .

Calculation:

Consider the function is

  $A$ is $3$ units above $y=-2$ so $A\text{'}$ should be $3$ units below $y=-2$ , $\left(1,-2-3\right)\Rightarrow \left(1,-5\right)$ .

  $B$ is $3$ units above $y=-2$ so $B\text{'}$ should be $3$ units below $y=-2$ , $\left(2,-2\right)$

  $C$ is $4$ units above $y=-2$ so $B\text{'}$ should be $4$ units below $y=-2$ , $\left(7,-2-4\Rightarrow \left(7,-6\right)\right)$

The image and connect to obtain the reflected image as shown in the figure (1)

Therefore, the angle is $\Delta BCD$ above solution.
