Q:
# What is a closed plane figure with three or more line segments?

A:
### Quick Answer

**A closed plane figure with three line segments is called a triangle.** If the closed plane figure has more than three line segments, it is called a polygon. The word “poly” means “many,” and there are different names for such figures.

A closed plane figure with four line segments is called a quadrilateral. This is the most common type of closed plane figure in geometry. A parallelogram, a rectangle, a square, a rhombus and a trapezium are all examples of quadrilaterals.

A closed plane figure with five sides is called a pentagon. A six and seven-sided figure is called a hexagon and a heptagon respectively. Similarly, a decagon has ten sides, and an octagon has eight sides.

Q:
## What is the side splitter theorem?

A:

Full Answer >**The side splitter theorem states that if a line parallel to one side of a triangle intersects with the other two sides, it divides those two sides proportionally.**This theorem can be used to solve many similar triangle math problems.Filed Under: -
Q:
## What is an oblique line?

A:An oblique line is one that is neither parallel nor perpendicular to another line or figure. The oblique line intersects the other line or figure at some point, so it is not parallel to it.

Q:
## What is the perpendicular bisector theorem?

A:

Full Answer >**The perpendicular bisector theorem is applicable for line segments.**The theorem states that the perpendicular bisector is a line that represents the locus of points that are equidistant from the endpoints of the line segment that it intersects.Filed Under: -
Q:
## What are parallel line segments?

A:

Full Answer >**Parallel line segments are any two line segments that run parallel to each other, which means that they will never cross.**The length or thickness of each line does not matter.Filed Under:
