1 answer

To find the coordinates of the transformed triangle \( A''B''C'' \) and determine in which quadrant it will lie, we need to apply the transformations step-by-step.

Step 1: First Transformation

The first transformation is given by the rule:

\[ (x, y) \rightarrow (x + 4, y - 6) \]

Let's apply this transformation to each vertex of triangle \( ABC \):

  1. Point A: \[ A(-8, 4) \rightarrow (-8 + 4, 4 - 6) = (-4, -2) \]

  2. Point B: \[ B(-5, 8) \rightarrow (-5 + 4, 8 - 6) = (-1, 2) \]

  3. Point C: \[ C(-3, 3) \rightarrow (-3 + 4, 3 - 6) = (1, -3) \]

So, after the first transformation, the coordinates of triangle \( A'B'C' \) are:

  • \( A'(-4, -2) \)
  • \( B'(-1, 2) \)
  • \( C'(1, -3) \)

Step 2: Second Transformation

The second transformation is defined by the rule:

\[ (x, y) \rightarrow (x + 5, y - 3) \]

Now, we apply this transformation to each point of triangle \( A'B'C' \):

  1. Point A': \[ A'(-4, -2) \rightarrow (-4 + 5, -2 - 3) = (1, -5) \]

  2. Point B': \[ B'(-1, 2) \rightarrow (-1 + 5, 2 - 3) = (4, -1) \]

  3. Point C': \[ C'(1, -3) \rightarrow (1 + 5, -3 - 3) = (6, -6) \]

So, after the second transformation, the coordinates of triangle \( A''B''C'' \) are:

  • \( A''(1, -5) \)
  • \( B''(4, -1) \)
  • \( C''(6, -6) \)

Step 3: Predicting the Quadrant

Now, we need to determine the quadrant where triangle \( A''B''C'' \) is located.

  1. Point A''(1, -5): \( x > 0 \) and \( y < 0 \) (Quadrant IV)
  2. Point B''(4, -1): \( x > 0 \) and \( y < 0 \) (Quadrant IV)
  3. Point C''(6, -6): \( x > 0 \) and \( y < 0 \) (Quadrant IV)

All three points are in Quadrant IV.

Conclusion

The coordinates of triangle \( A''B''C'' \) are:

  • \( A''(1, -5) \)
  • \( B''(4, -1) \)
  • \( C''(6, -6) \)

After the transformations, triangle \( A''B''C'' \) will be located entirely in Quadrant IV.
