Which statements about the diagram are true? select three

DE+EF>DF

5<DF<13

∆DEF in a scalene triangle.

Step-by-step explanation:

When combined, DE and EF must be longer than DF, or else the three sides will not all be connected, and the shape will no longer be a triangle.

DE+EF>DF

When combined, DE and EF must be longer than DF, or else the three sides will not all be connected, and the shape will no longer be a triangle.

When combined, DE and DF must be longer than EF, or else the three sides will not all be connected, and the shape will no longer be a triangle.

DE+EF=13

DF<13

DE+DF>EF

4+DF>9

DF>5

5<DF<13

The |, ||, and ||| on the lines EF, DE, and DF means that all of the sides have different lengths. This means that the triangle is scalene.

∆DEF is a scalene triangle.

I hope this helps. :)
