Two $triangle$triangle are placed on a Cartesian plane, where the x- and y- axes are labeled and range from -10 to 10. These $triangle$triangle, $ABC$ABC and $A'B'C'$A′B′C′, have the same shape and size but are situated differently. The coordinates of the vertices are not explicitly given. The vertices of $triangle$triangle $ABC$ABC are located at A $\left(-2,3\right)$(−2,3), B $\left(2,1\right)$(2,1), C $\left(4,-4\right)$(4,−4), and D $\left(4,-4\right)$(4,−4). Similarly, the vertices of $triangle$triangle $A'B'C'$A′B′C′ are positioned at A' $\left(1,5\right)$(1,5), B' $\left(5,3\right)$(5,3), C' $\left(7,-2\right)$(7,−2), and D' $\left(7,-2\right)$(7,−2).
