Thank you for the opportunity to help you with your question!

Water is considered to be a polar molecule owing to the shape. In this case, water is composed of a positively charged side and a negatively charged side. A water molecule is made up of two hydrogen atoms covalently bonded to one oxygen atom. As such, the bond type is covalent. Additionally, a water molecule may further be explained as being polar through the consideration of the charges which culminate in the shape. Hydrogen atoms share electrons and thus tend to stick close to the oxygen atoms. Consequently, this gives the hydrogen atoms a positive charge  on the outside as their affinity for oxygen electrons is high. Conversely, oxygen atoms contain two electrons. As a result,they tend to have a lower affinity for hydrogen and this gives them a negative charge in the outside.
