Practice problem
We are given △IJK≅△RST\triangle IJK \cong \triangle RST△IJK≅△RST. Which of the following must be true, using the given information?
∠IKJ≅∠RTS\angle IKJ \cong \angle RTS∠IKJ≅∠RTS
∠IKJ≅∠RST\angle IKJ \cong \angle RST∠IKJ≅∠RST
IK‾≅RT‾\overline{IK} \cong \overline{RT}IK≅RT
JK‾≅RS‾\overline{JK} \cong \overline{RS}JK≅RS
Type a concept, like “slope” or “photosynthesis”.
