Answer: A rhombus has order of rotational symmetry of 2
Step-by-step explanation:
We know that a geometric figure has rotational symmetry if it maps onto itself under rotation about an angle at its center.
The order of rotational symmetry is the number of times the geometric figure maps onto itself during a rotation of 360°.
[ At 180° and 360° it maps onto itself]
A rhombus maps onto itself two times during a rotation of 360°
Hence, A rhombus has order of rotational symmetry of 2.
Step-by-step explanation:
Lets look at each of the options one by one:
Price System: In this system markets allocate resources through the price mechanism. An increase in demand raises price and encourages businesses to use more resources into the production of that good or service. In this system the government limits itself to protecting property rights of people and businesses using the legal system and protecting the value of money or the value of a currency.
Authoritarian System: In this system it is associated with a communist system. The scarce resources are owned by the government. The state allocates resources, and sets production targets and growth rates according to its own view of people's wants. They have their own idea of demand.
By comparing two systems it can be seen that Price System automatically moves resources to where they are most needed. So, price system is more efficient than authoritarian means.
