Classify triangle ABC. (by angles and sides). (You will need to find the
missing angles first.)

Given: x + y = 6. if xe (-15, -6, -1), then which of the following sets of ordered pairs are solutions? © {(-15, -21), (-6, -12), (-1, -7)} [(-15, 21), (-6, , 7)} {(-15, 21), (-6, 12), (-1, -7)}

Triangle xyz has vertices x(1,3), y(0,0)

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles
