### What figure has 2 pairs of parallel sides?

parallelogram

A parallelogram is a quadrilateral with 2 pairs of parallel sides. In these figures, sides of the same color are parallel to each other. A shape with four sides of equal length. The shape has two sets of parallel sides and does not have right angles.

**Does a polygon have 2 pairs of parallel sides?**

Parallelograms are interesting shapes with many interesting properties. Even the shape rectangle is a type of parallelogram.

**Does a hexagon have 2 pairs of parallel sides?**

A regular hexagon, which means a hexagon with equal sides and equal interior angles, is the shape that has 3 pairs of parallel sides.

## Why does a pentagon have no parallel lines?

Regular pentagons do not have parallel sides. Just like any regular polygon, going around a pentagon completes one full circle, so the exterior angles are found by dividing 360° by the number of sides, in this case, 360°5 = 72° 360 ° 5 = 72 ° .

### What is a 7 sided shape called?

heptagon

In geometry, a heptagon is a seven-sided polygon or 7-gon. The heptagon is sometimes referred to as the septagon, using “sept-” (an elision of septua-, a Latin-derived numerical prefix, rather than hepta-, a Greek-derived numerical prefix; both are cognate) together with the Greek suffix “-agon” meaning angle.

**How do you know if sides are parallel?**

If two lines are cut by a transversal so the alternate exterior angles are congruent, then the lines are parallel. If two lines are cut by a transversal so the consecutive interior angles are supplementary, then the lines are parallel. If two lines are parallel to the same line, then they are parallel to each other.

**Is any 3 sided polygon a triangle?**

A three-sided polygon is a triangle. There are several different types of triangle (see diagram), including: Equilateral – all the sides are equal lengths, and all the internal angles are 60°. Isosceles – has two equal sides, with the third one a different length.

## Can a rhombus have 4 right angles?

A rhombus is defined as a parallelogram with four equal sides. Is a rhombus always a rectangle? No, because a rhombus does not have to have 4 right angles. Kites have two pairs of adjacent sides that are equal.

### Does a triangle have parallel lines?

A triangle is a geometric shape that always has three sides and three angles. Triangles have zero pairs of parallel lines.

**Do hexagon have parallel lines?**

Since it’s a regular hexagon (six-sided polygon), we know it’s made up of sets of parallel lines. The interior angle of the hexagon is supplementary to ∠1 because they form a linear pair, so the measure of one interior angle of the hexagon is 180 – m∠1, or 120°.

**How many pairs of parallel sides are in a pentagon?**

When searching online try using the word polygon rather than a pentagon. a regular pentagon will have 0 parallel lines, but an irregular pentagon can have 2 (1 pair) or even 4 (2 pairs) parallel lines.

## How many perpendicular lines does a pentagon have?

For pentagon the perpendicular bisector of each side forms a symmetry. So,there are 5 lines of symmetry. For rhombus,the two diagonal lines are lines of symmetry.

### Does a pentagon have an obtuse angle?

Since an obtuse is any angle greater than 90∘ but less than 180∘, this means that 108∘ must be an obtuse angle. Since there are 5 108∘ angles in a pentagon, then there are 5 obtuse angles in a regular pentagon. ∴, there are 5 obtuse angles in a regular pentagon.

**How many adjacent sides does a pentagon have?**

A pentagon is any shape that has five sides. The simple pentagon has five equal sides which join to the neighboring sides at equal angles.
