Question 563210
<font face="Times New Roman" size="+2">
Typing in all caps is the electronic communication equivalent of shouting.  It is both rude and annoying.  Please don't apologize or provide a lame excuse like "I didn't notice the Caps Lock was on..."  Just don't do it any more.


Since 1 and 4 are supplementary, the measure of 1 plus the measure of 4 is 180 degrees.  Hence 180 minus the measure of 1 is 4.  Likewise, the measure of 2 plus the measure of 3 is 180.  Substituting since 1 and 3 are congruent, the measure of 2 plus the measure of 1 is 180.  Hence, 180 minus the measure of 1 is 2.  The measure of 4 and the measure of 2 are the same, so they have to be congruent.
