Answer:
Step-by-step explanation:
Since the x-axis is the line of symmetry, the missing vertex is the reflection of the given vertex over the line of symmetry.
- The given vertex is (- 2, 4)
- Its reflection is (- 2, -4), only y-coordinate changes to opposite
Connect these points with the vertex on the x-axis to complete the triangle.
