C. 2
D. 5

### 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.
