Two lines are diagonal and are both marked with a single arrow to indicate the lines are parallel. The diagonal lines start in the bottom left and end in the top right. A horizontal...
Two or more lines that meet at a point are called intersecting lines. That point would be on each of these lines. In Figure 1, lines l and m intersect at Q. Figure 1 Intersecting lines. Perpendicular lines. Two lines that intersect and form right angles are called perpendicular lines. The symbol ⊥ is used to denote perpendicular lines. In ...
Sep 5, 2021 · \(\overleftrightarrow{AB} || \overleftrightarrow{CD}\) since the arrows indicate parallel lines. \(x^{\circ} = 40^{\circ}\) because alternate interior angles of parallel lines are equal. \(y^{\circ} = z^{\circ} = 180^{\circ} - 40^{\circ} = 140^{\circ}\). Answer: \(x = 40, y = 140, z = 140\).
Intersecting lines are when two or more lines cross each other in a plane at a crossroads. There is one common point that lies on both lines, which is called the point of intersection. Two straight intersecting lines meet and create pairs of vertically opposite angles (or vertical angles).
Parallel Lines. Two lines are said to be parallel when they do not meet at any point in a plane or which do not intersects each other. In the figure, lines PQ and RS are parallel to each other. Transversal Line. When a line intersects two lines at distinct points, it is called a transversal.

Finding angles. Intersecting lines are lines that cross each other. Parallel lines are lines that never cross each other - they keep the same distance apart from each other. When two...

What if two lines are parallel?
When two parallel lines are crossed by another line, known as a transversal, a fascinating world of angles is revealed. Imagine two roads running side by side, with a third road intersecting them at different points – that's what happens when parallel lines meet a transversal.
