Answer:
Option A is correct.
2 : 1
Step-by-step explanation:
Similar triangle:
Two triangles are similar if their corresponding sides are in proportion or side are of equal length.
As per the statement:
Given: ΔABC and ΔDEF are similar triangle.
Triangle ABC is shown with AC measuring 4 and BC measuring 5.
Triangle DEF is shown with side DF measuring 2.
Then by definition of similar triangles:
[tex]\frac{AB}{DE} = \frac{BC}{EF} = \frac{AC}{DF}[/tex]
Substitute the given value we have;
[tex]\frac{AC}{DF} = \frac{4}{2} = \frac{2}{1}[/tex] = 2 : 1
therefore, the similarity ratio of ΔABC to ΔDEF is, 2 : 1
