Madison is given rectangle ABCD with one diagonal BD

Lena [83]

Answer:

i. Rotate

ii. Translates

Step-by-step explanation:

Rigid transformations are the methods required in which the orientation, dimension, position, or size of a given figure can be transformed. Some types of rigid transformation are: rotation, translation, reflection, etc.

From the given question, the two rigid transformation procedure required for Madison to prove that ΔABD ≅ ΔCDB by rigid transformations are: rotation and translation.

Madison decides to rotate ΔABD $180^{o}$ about point B to create triangle A'B'D'. Next she translates A'B'D' along diagonal BD until point B' from ΔA'B'D' lines up with point d from ΔCDB.
