Geometry Flashcards
Metric System
Is a system of measurements that uses the metre, litre and gram as base units of length (distance), capacity (volume), and weight (mass).
As we move to the right, each unit is 10 times smaller.
Perimeter
The distance around the outside of a 2D shape.
Area
The space occupied by a flat 2D of an object, measured in unit squares.
Volume
The amount of 3D space, measured in cubic units, that an object occupies.
Surface Area
The total surface area of all the individual faces of a 3D object.
Prism
Is a 3D shape with two identical shapes facing each other.
These identical shapes are called ‘bases’.
The other faces of a prism are rectangles.
Face
Is a flat surface of a 3D shape.
Edges
The line segment that joins two vertices together and boarders two faces.
Vertices (Vertex)
The point where lines meet. Vertex means corner. Vertices is the plural.
Net
A flat shape made up of the faces of a 3D object that can be folded up into a 3D solid.
