A scalene triangle has sides of all different lengths, and all different angles.

Honeycomb, snowflakes and insect eyes all include hexagons.

#3. Leaves come in many shapes and sizes. What shape is a cordate leaf?

Cordate leaves are heart shaped.

#4. One of the essential minerals in the human body is salt. How much salt (NaCl) is in the average adult human body?

The average adult human body contains about 250 grams of salt, roughly the weight of a block of butter. If you don’t have enough salt, your body suffers an electrolyte imbalance called hyponatremia.

#5. What shape is our solar system?

Our solar system’s ‘bubble’, carved into space by solar wind, is actually a squashed crescent shape. It has also been compared to a deflated croissant.
