# ExplanationTo map one triangle to another using rigid motions, we need to understand what rigid motions are and how they can be applied. Rigid motions in geometry include translations, rotations, reflections, or a combination of these. These transformations preserve the distance between points, meaning the shape and size of figures do not change after the transformation. To determine the specific composition of rigid motions that maps
to
, we must consider the following steps:1. **Identify Corresponding Points**: First, identify which points in
correspond to points in
. This step is crucial for understanding how the triangle has been moved.2. **Determine the Type of Rigid Motion**: - **Translation**: If
has been moved to a new location without being rotated or flipped, then a translation has occurred. - **Rotation**: If
has been turned around a point (not necessarily one of its vertices) to match
, then a rotation has occurred. The center and angle of rotation must be determined. - **Reflection**: If
has been flipped over a line (the line of reflection) to match
, then a reflection has occurred. The line of reflection must be identified. - **Combination**: Sometimes, a combination of these motions is necessary. For example, a reflection followed by a translation.3. **Apply the Rigid Motion(s)**: After determining the type(s) of rigid motion needed, apply them systematically to
to see if
is obtained. This step may require trial and error or geometric constructions to find the exact motions.Since the specific positions of
and
are not provided, we cannot determine the exact composition of rigid motions needed. However, the process described above outlines how one would approach this problem given specific triangle positions.# AnswerWithout specific information on the positions of
and
, it is impossible to determine the exact composition of rigid motions required.
