Explanation:

Supplementary angles are those angles, which degree measures add up to 180°.

Complementary angles are those angles, which degree measures add up to 90°.

Vertical angles are two opposite angles formed when two lines intersect.

1. Two right angles are always supplementary.

Right angle has the degree measure of 90°, then the sum of measures of  two right angles is always 180°.

2. Two angles that are nonadjacent are sometimes vertical.

They are vertical when the sides of these angles form two intersecting lines, in other cases they are not vertical.

3.  Two angles that are supplementary are never complementary.

If two angles are supplementary, then their measures add up to 180°. 180 is not equal to 90°, so these angles cannot be complementary.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.

answer: from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion—that we here highly resolve that these dead shall not have died in vain, that this nation under god shall have a new birth of freedom, and that government of the people
