Transformation involves changing the position of a shape.
Reflecting triangle GBC across line BC will take GBC onto ABC
From the diagram, we have the following highlights
- Sides AB and GB are corresponding, and congruent
- Sides AC and GC are corresponding, and congruent
- Angles ABC and GBC are corresponding, and congruent
- Both triangles have a common side length (BC)
The above highlights mean that:
Both triangles are not just similar, they are also congruent.
So, when any of the triangles is reflected across the common side length, it will be mapped onto the other triangle.
Hence, the rigid reflection that will take triangle GBC onto triangle ABC is reflection across line BC
