Chapter 7- Symmetry and Surface Area Flashcards
1
Q
Symmetry
A
An object or image has symmetry if it fits into itself by reflection or rotation.
2
Q
Line of Symmetry
A
A line running through an object that halves on each side of the line.
3
Q
Rotation Symmetry
A
Occurs when a shape can be turned about it’s outline more than once in a turn.
4
Q
Centre of rotation
A
The point about which the rotation of an object or design turns.
5
Q
Order of Rotation
A
The number of times a shape fits onto itself in one turn.
6
Q
Surface Area
A
The number of square units needed to cover a 3D object.
7
Q
Transformation
A
A change in a figure that results in a different position.
