Answer:
The lines are called perpendicular lines.
Explanation:
In geometry, the lines with angle 90 degree between them is called as perpendicularity. When the straight lines is divided into two congruent angles, then it forms perpendicular angles. The lines always forms “T” shape.
- In circle, the angle between the diameter and the tangent to the circle is perpendicular angle.
- The minor axis and major axis of the ellipse are in perpendicular angle.
- In parabola, the symmetry axis is perpendicular to latus rectum, tangent, and directrix.
- In square, there are four perpendicular angles.
