A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel .

Does parallel mean equal sides?

Parallel lines stay the same distance apart and will never intersect (cross over). The green lines mark the sides of equal (the same) length, and the blue arrows mark the sides that are parallel lines. Quadrilaterals with perpendicular lines have sides that meet at a right angle (90°).

What is parallel in math?

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.

What is example of parallel lines?

The real-life examples of parallel lines include railroad tracks, the edges of sidewalks, rails of a ladder, never-ending rail tracks, opposite sides of a ruler, opposite edges of a pen, eraser, etc.

Why does parallel mean?

: lying or moving in the same direction but always the same distance apart parallel lines Train tracks are parallel. 3 : a way in which things are similar The parallel between their lives is obvious. 4 : equal entry 3 It is a masterpiece without parallel.

What shapes have no parallel sides?

Explanation: The American term for such a quadrilateral is a trapezium, and the British term is a trapezoid. It is a quadrilateral that has no parallel sides.

Does a rectangle have parallel sides?

What is a rectangle? A rectangle is a quadrilateral with 4 right angles. A shape with four sides of equal length. The shape has two sets of parallel sides and has four right angles.

Does parallel mean opposite?

In math, parallel means two lines that never intersect — think of an equal sign. Figuratively, parallel means similar, or happening at the same time.

What are perpendicular sides?

Two distinct lines intersecting each other at 90° or a right angle are called perpendicular lines. Example: Here, AB is perpendicular to XY because AB and XY intersect each other at 90°. Non-Example: The two lines are parallel and do not intersect each other.

What are parallel angles?

What are angles in parallel lines? Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal. We can use the information given in the diagram to find any angle around the intersecting transversal.

What is it called when two lines cross?

When two or more lines cross each other in a plane, they are called intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is called the point of intersection.
