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.Know More
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.Learn more about Geometry
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.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.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.Full Answer >
In geometry, a plane is defined as a flat, infinite surface. It has infinite length and width but no thickness. A plane is thus a two-dimensional, boundless surface and a subset of space.Full Answer >
