are corresponding angles supplementary
No, corresponding angles don't have to add up to anything, but supplementary add up to 180 degrees.
However, if the angles are supplementary, the sum of their measures is 180° since supplementary angles can form a linear pair and their measures sum to 180° so ......x+x=180° which means that 2x=180° divide both sides by 2 so x=90° and that means all these angles are right angles.
