identify any congruent figures in the coordinate plane. explain.

Congruent figures are:
Rectangle IJGH and rectangle QRPN
Triangle EDF and triangle BAC
Triangle LKP and triangle TSU
Solution:
To identify the congruent figures in the given figures:
Two polygons are congruent if they have the same size and same shape.
(1) Rectangle IJGH and rectangle QRPN are same shape.
IH ≅ QP
IJ ≅ QR
JG ≅ RN
HG ≅ PN
Therefore rectangle IJGH and rectangle QRPN are congruent figures.
(2) Triangle EDF and triangle BAC
ED ≅ BA
DF ≅ AC
EF ≅ BC
Therefore triangle EDF and triangle BAC are congruent figures.
(3) Triangle LKP and triangle TSU
LK ≅ TS
KP ≅ SU
LM ≅ TU
Therefore triangle LKP and triangle TSU are congruent figures.
