A pair of lines that intersect each other perfectly form 90 degree angles are perpendicular.
Anything else is just intersecting lines

Lines that intersect at right angles.

No, skew lines are not perpendicular. Perpendicular lines intersect at an angle of ninety degrees, while skew lines never intersect (think in three dimensions or higher).
Opposite angles, also known as vertical angles, are formed when two lines intersect. They are equal in value, meaning that the measure of one angle is the same as the measure of the angle directly across from it. This property arises from the fact that the lines create two pairs of angles that share a common vertex. Consequently, if one angle measures 50 degrees, the opposite angle will also measure 50 degrees.

If lines intersect they CANNOT BE PARALLEL. Speak to your teacher!
False because they intersect at right angles.
Perpendicular lines are lines that intersect at a right angle (90 degrees).
Lines that intersect at right angles.
An angle of 90 degrees is a right angle when perpendicular lines intersect each other.
Not necessarily. Consider two lines that intersect at some angle other than 90 degrees. Then the angle of intersection is not 90 degrees means they are not perpendicular. But, because they intersect, neither are they parallel.
Form right angles
It is a perpendicular line that intercepts another line at 90 degrees.
59 degree
"right angle" is two lines that intersect at 90 degrees "acute angle" is when 2 lines meet at less than 90 degrees "obtuse angle" is when lines meet at an angle more than 90 degrees , a straight angle is when 2 lines meet at exactly 180 degrees.
