If two lines are perpendicular, then they intersect to form angles.

acute
complementary
right
obtuse

Third option.

Step-by-step explanation:

You can know the answer by remembering the definition of perpendicular lines.

By definition, perpendicular lines are those lines that intersect at a right angle (This is an angle that measures 90 degrees).

In the equations of lines, for example, you can identify if the lines are perpendicular by comparing their slopes. If the slopes are  opposite reciprocals, then the lines are perpendicular (In other words, they form an angle that measures 90 degrees).

Therefore: If two lines are perpendicular, then they intersect to form right angles.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
