## Vertex, vertices

Vertex, vertices A vertex is a point where two straight lines or rays meet to form an angle, the edges of a solid figure meet and the corners of polygons and polyhedra are vertices. Vertices are found in angles, which are measured in degrees. Pentagon Triangular Pyramid Rectangular […]

## Bar graph (column graph)

Bar graph (column graph) A bar graph is a graphical representation of data, quantities, or numbers using bars or strips. They are used to compare and contrast different types of data, frequencies, or other measures of distinct categories of data. A bar graph is a graph that uses horizontal or vertical bars to display countable data. […]

## Plane, plane shapes

Plane, plane shapes Plane shapes are two-dimensional geometric figures: they have length and width but they have no depth. Plane shapes exist on a flat surface, known as a plane. Here are some plane shapes examples: […]

## Trapezium, trapezoid

Trapezium, trapezoid A trapezium (UK) or a trapezoid (US) A trapezium is a quadrilateral having two parallel sides of unequal length and the other two sides are non-parallel. The parallel sides of a trapezium are called bases (AD and DC or a and b) and the non-parallel sides of a trapezium are called legs (AD and […]
