Which statements about the diagram are true? check all that apply. de + ef > df def is an isosceles triangle 5 < df < 13 de + df < ef def is a scalene triangle

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).
