Triangle D accurately represents the reflection of triangle A across line m. In reflections, corresponding points are equidistant from the line of reflection, maintaining the same angles and side lengths.
Triangle D represents the reflection of triangle A across line m. In a reflection, corresponding points on the original and reflected shapes are equidistant from the line of reflection. In triangle D, each vertex is equidistant from line m as the corresponding vertex in triangle A.
The sides and angles in triangle D maintain the same measures as those in triangle A, ensuring that the reflection is accurate. Line m serves as the axis of symmetry, preserving the geometric relationships between the corresponding elements of the two triangles. Thus, triangle D is a faithful reflection of triangle A across line m.
