Will give brainiest if you get it ! is the following definition of supplementary reversible. if yes, write it as a true biconditional. supplementary angles are two angles whose measures sum to 180 a)yes, if angles are supplementary, then their measures sum to 180 b)yes, angles are supplementary if (and only if) their measures sum to 180 c)yes, angles are supplementary if their measures sum to 180 d)the statement is not reversible

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
