Whether the given sentence is true or false.
Answer to Problem 7SGR
True.
Explanation of Solution
Given:
Three types of congruence transformations are rotation, reflection and translation.
Calculation:
A congruence transformation is the one in which the position may differ from that of the pre-image, but the two figures remain congruent.
A reflection is the transformation over a line. Each point of the pre-image and its image are at the same distance apart from the line of reflection.
A translation is a transformation which moves all the points of the original figure the same distance in the same direction.
A rotation is a transformation around a fixed point. Hence, these are the three types of congruence translations. Hence, the statement is true.
