There are infinitely many such. A valentine heart would be one well-known. example.
Multiply the VAT figure by 5 ie: VAT amount £20 x 5 gives you a net figure of £100.00.
A mole is basically an amount of something. In chemistry, a mole is known as a chemical mole. To figure out the weight of a mole, you figure out the molar mass.
Axisymmetry is a form of symmetry around an axis - also known as rotational symmetry.
A tetrad has rotational symmetry of order 4. It also has no lines of symmetry. It is also known as a swastica.
Lines which lie on the same plane and have the same length are known as symmetry lines
Jellyfish and sea anemones are known for having radial symmetry.
Vertebrates in general have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down
Radial symmetry is common to the group of invertebrates known as mollusks.
It has rotational symmetry order 2. Its is also known as a diamond and is a special type of rectangle
Tigers have bilateral symmetry. Bilateral symmetry means something has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
