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
Altitude in geometry (also known as height) refers to a segment that extends from any vertex of a triangle and is perpendicular to the line found on the opposite side. This term is also employed to refer to the length of this segment.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 >
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 >
A plane can be regarded as a single letter, written in upper case and in cursive lettering, such as plane Q. It can also be named by identifying three points on the plane that do not form a straight line.Full Answer >
