Practice problem
Which of the following statements shows congruent angles?
If m∠x=m∠ym\angle{x}=m\angle{y}m∠x=m∠y, then ∠x≅∠y\angle{x}\cong\angle{y}∠x≅∠y
If ∠x≅∠y\angle{x}\cong\angle{y}∠x≅∠y, then m∠x=m∠ym\angle{x}=m\angle{y}m∠x=m∠y
If m∠x=m∠ym\angle{x}=m\angle{y}m∠x=m∠y, then ∠x≆∠y\angle{x}\ncong\angle{y}∠x≆∠y
If ∠x≆∠y\angle{x}\ncong\angle{y}∠x≆∠y, then m∠x=m∠ym\angle{x}=m\angle{y}m∠x=m∠y
Type a concept, like “slope” or “photosynthesis”.
