A triangle is a geometric shape that always has three sides and three angles. Triangles have zero pairs of parallel lines. They usually have zero pairs of perpendicular lines.
How many parallel side Can a triangle have?
A | B |

How many pairs of parallel lines does a square have? | A square has 2 pairs of parallel lines. |
How many pairs of parallel lines does a triangle have? | A triangle has no parallel lines. |
What polygon has six sides and six angles? | HEXA = 6 so a hexagon has 6 sides and six angles. |
Can any two sides of a triangle can be parallel?
Yes, it is applicable for every type of triangle.
Are parallel sides?
Two sides or lines are parallel if they are lines that are always the same distance from each other and will never intersect or touch. … If you and a buddy each walked on a line, the two of you would never cross paths, and if you kept pace with each other, you would always be the same distance apart.

How do you know if triangles are parallel?
Determining if Two Lines are Parallel
Use the Triangle Proportionality Converse. If the ratios are equal, then the lines are parallel.

Does a circle have parallel lines?
Well circles don’t have sides at all, so no parallel sides.
What shapes have no parallel sides?
Triangles are shapes that have no parallel sides. All triangles will have three sides and it is impossible for any of them to be parallel. If two lines out of three were parallel, it would be impossible to draw the shape.
Does a kite have parallel sides?
Kites have no parallel sides, but they do have congruent sides. Kites are defined by two pairs of congruent sides that are adjacent to each other, instead of opposite each other.
Which shape has parallel sides?
Name | Definition | Example |
---|---|---|
Parallelogram | 2 pairs of parallel sides | Created with Raphaël |
Trapezoid | Exactly 1 pair of parallel sides | Created with Raphaël |
Rectangle | 4 right angles | Created with Raphaël |
Rhombus | 4 equal sides | Created with Raphaël |
What is the three parallels Theorem?
Three Parallel Lines Theorem
If three parallel lines intersect two transversals, then they divide the transversals proportionally.
How do you prove two sides parallel?
Theorem 3.6 Alternate Interior Angles Converse If two lines are cut by a transversal so the alternate interior angles are congruent, then the lines are parallel. If two lines are cut by a transversal so the alternate exterior angles are congruent, then the lines are parallel.

Do Quadrilaterals always have parallel sides?
Remember, if you see the word quadrilateral, it does not necessarily mean a figure with special properties like a square or rectangle! In word problems, be careful not to assume that a quadrilateral has parallel sides or equal sides unless that is stated.
What is ASA theorem in geometry?
The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
Which shape has only one pair of parallel sides?
The exclusive definition of a trapezoid states that a trapezoid has exactly one pair of opposite sides parallel.
What are the parallel sides of a trapezium?
The parallel sides of a trapezium are called bases and the non-parallel sides of a trapezium are called legs. It is also called a trapezoid. Sometimes the parallelogram is also called a trapezoid with two parallel sides.

Does a diamond shape have parallel sides?
A diamond is a quadrilateral, a 2-dimensional flat figure that has four closed, straight sides. But a diamond is also categorized as rhombus, because it has four equal sides and its opposite angles are equal. And, because its opposite sides are parallel, it’s also considered to be a parallelogram.
Does pentagon have parallel sides?
A regular pentagon has no parallel or perpendicular sides, but a non-regular pentagon might have parallel and perpendicular sides. It all depends on the polygon.
What shape has 3 pairs of parallel sides?
The hexagon has three sets of parallel lines.
What has 2 pairs of parallel sides?
Parallelogram: A quadrilateral with 2 pairs of parallel sides.
Is a trapezoid isosceles?
Isosceles trapezoid | |

Properties | convex, cyclic |
Is parallelogram a trapezium?
A trapezium is not a parallelogram because a parallelogram has 2 pairs of parallel sides. But a trapezium only has 1 pair of parallel sides.
Do all Rhombuses have 2 pairs of parallel sides?
Every rhombus has two diagonals connecting pairs of opposite vertices, and two pairs of parallel sides.
Can there be 3 parallel lines?
There are two sets of parallel lines (one consisting of three parallel lines, the other of two), and we use different arrow symbols to differentiate them, much as we’d use hash marks for congruent line segments.
How do you draw three parallel lines?

Can you have 3 parallel lines?
We have shown that when we have three parallel lines, the ratios of the segments cut off on the transversal lines are the same: |AB|/|BC|=|DE|/|EF|. … So the distance between any two adjacent lines is the same. The distance is the length of a perpendicular line from one parallel line to another.
How do you write parallel lines?
Two lines are parallel lines if they do not intersect. The slopes of the lines are the same. f(x)=m1x+b1 and g(x)=m2x+b2 are parallel if m1=m2 f ( x ) = m 1 x + b 1 and g ( x ) = m 2 x + b 2 are parallel if m 1 = m 2 . If and only if b1=b2 b 1 = b 2 and m1=m2 m 1 = m 2 , we say the lines coincide.
Does congruent mean parallel?
If two parallel lines are cut by a transversal, then corresponding angles are congruent. If two lines are cut by a transversal and corresponding angles are congruent, then the lines are parallel.
What’s consecutive interior?
When two lines are cut by a transversal, the pair of angles on one side of the transversal and inside the two lines are called the consecutive interior angles.
How long is hypotenuse?
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
How do I find the third side of a triangle?

What is the longest side of a right triangle called?
We define the side of the triangle opposite from the right angle to be the hypotenuse, h. It is the longest side of the three sides of the right triangle. The word hypotenuse comes from two Greek words meaning to stretch, since this is the longest side.
