Determining Congruence

Determining Congruence 1.7 - Solution

arrow_back Return to Determining Congruence

Looking at the graph, we can see that and have the same shape and size. What separates them are their position and orientation on the coordinate plane. Therefore, they are congruent.

In vertex is above and In the corresponding vertex, is below and To line up their orientations, we can reflect in the axis.

Next, by translating the rotation of up unit and right units, we can map it onto

Therefore, the congruence transformation that maps to is a reflection in the axis followed by a translation up unit and right units.
