Joseph says that the square root of 144 has two values. Is he correct? Why or why not?
Yes, because 12 x 12 = 144 and -12 x -12 =144, so the square root of 144 is 12 AND -12.

Consider these two triangles: Triangle ABC has angles that measure 71 degrees and 62 degrees. Triangle DEF has angles that measure 47 and 62 degrees. Are these two triangles similar? WHY or WHY NOT?
They are similar, because the three angles in both triangles have the same measure.
