What shapes have a pair of parallel lines?
Lesson at a Glance Some shapes that have parallel sides include the parallelogram, the rectangle, the square, the trapezoid, the hexagon, and the octagon. A trapezoid has one pair of parallel sides.
Does a rhombus have 2 sets of parallel lines?
A rhombus is a special case of a parallelogram, because it fulfills the requirements of a parallelogram: a quadrilateral with two pairs of parallel sides. It goes above and beyond that to also have four equal-length sides, but it is still a type of parallelogram.
Does a rectangle have two pairs of parallel sides?
Answer: A rectangle has 2 pairs of parallel sides. In a rectangle, the two lines forming a pair of parallel sides are also congruent, unlike a parallelogram. Explanation: Just like a square, a rectangle has 4 sides at right angles forming 2 pairs of parallel sides.
How many sets of parallel lines are in a triangle?
5. A triangle is a geometric shape that always has three sides and three angles. Triangles have zero pairs of parallel lines.
How many right angles has a rhombus?
four
If a rhombus is a square, all four of its angles are right. Otherwise, all angles are either acute or obtuse, but not right.
What are the sides of a shape that are parallel?
Parallel sides are two or more sides on a shape that are parallel. We mark a set of parallel sides on a shape with an arrow on each side. We mark further sets of parallel sides with two or more arrows if we have already marked a set with one arrow each. Parallel sides go in exactly the same direction and do not touch.
How many arrows are on each side of a parallel shape?
Usually one arrow is drawn on each side that is parallel. However if the shape has another set of parallel sides, then two arrows are drawn on these sides.
How to write about parallel lines and sides?
You can also write about parallel lines or sides using a symbol. When drawing figures, you indicate pairs of parallel sides by drawing little matching arrowheads on the two parallel opposite sides. If you have, say, a rectangle (with two pairs of parallel sides) you can use single arrowheads for one pair and double arrowheads for the other:
What happens when you draw two parallel sides?
Usually one arrow is drawn on each side that is parallel. However if the shape has another set of parallel sides, then two arrows are drawn on these sides. If there is another set of parallel sides, then three arrows would be drawn etc. For example, the square below has two pairs of parallel sides.
