Reflect triangle π΄BC across the vertical line, parallel to the π¦π¦-axis, going through point (1, 0). Label the transformed points π΄, π΅, πΆ as π΄β², π΅β², πΆβ², respectively.
Reflect triangle π΄β²π΅β²πΆβ² across the horizontal line, parallel to the π₯π₯-axis going through point (0, β1). Label the transformed points of π΄β², π΅β², πΆβ² as π΄β²β², π΅β²β², πΆβ²β², respectively.
