They are perpendicular lines
Perpendicular lines intersect each other at right angles.
They are called perpendicular lines that intersect each other at right angles.
A straight line segment can be drawn by joining any two points.A straight line segment can be extended indefinitely in a straight line.Given a straight line segment, a circle can be drawn using the segment as radius and one endpoint as center.All right angles are congruent.If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough.

Lines that intersect each other at right angles are called perpendicular lines
They are perpendicular lines
Perpendicular lines intersect each other at right angles.
They are called perpendicular lines that intersect each other at right angles.
Extend all the lines of a right-angled triangle with sides of 3, 4 and 5 units. The extension of the lines forming the right angle will produce 3 other right angles. The extension of the lines forming the other two angles will produce 6 other angles. This gives a total of 12 angles, 4 of which are acute, 4 right and 4 obtuse.
Perpendicular lines
right angles are perpendicular lines that intercept each other at right angles which is 90 degrees
Parallel refers to lines and not angles A right angle is formed by 2 lines that are perpendicular to each other and not parallel If you already have a line and you draw two lines which are at right angles to it, those two lines are parallel.
Perpendicular lines intersect each other at right angles
A semicircle itself does not have any right angles; it is a half-circle. However, if you consider the angle formed at the endpoints of the diameter when a line is drawn to any point on the arc of the semicircle, that angle is a right angle (90 degrees). Thus, while the semicircle itself has no right angles, it can form right angles with lines drawn to points on its arc.
Two lines that intersect and form 90-degree angles (right angles) are "perpendicular" to each other. You would call them "perpendicular lines."
