The slope of line segment AC the same as the slope of line segment DF in the figure below because AB/EF = BC/DE.
What is the congruent triangle?
Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
We need to find the proportionality statement for the ratio of the sides of the triangles.
If two triangles are similar, then the corresponding sides are proportional.
ABC ≈ DEF,
Here AB, BC, and AC are corresponding sides of DE, EF, and DF respectively.
Using the definition of similarity we ge
AB = 2
EF = 5
BC = 1
DE = 2.5
2/5 = 0.4
1/2.5 = 0.4
The equation AB/EF = BC/DE is correct. All of the others are not.
