Which column represents the correct method for the proof of the following statement? If two angles form a linear pair, then they share a common ray.
Column A
1. Assume the angles do not form a
linear pair
2. If the angles do not form a linear
pair, then they are not adjacent
Column B
1. Assume the angles do not share a
common ray
2. If the angles do not share a
common ray, then they are not
adjacent
3. If two angles are not adjacent, then
they cannot form a linear pair
4. If two angles do not share a
common ray, then they do not form
a linear pair
3. If two angles are not adjacent then
they do not have a common ray
4. If two angles do not form a linear
pair, then they do not have a
common ray
A column A
B. column B
C. both column A and column B
D. neither column A nor column B
