These two scalene triangles are similar with a scale of 5:2. What is true about these figures?

Solution:

A scalene triangle is a triangle having all three sides of different lengths, and all three angles of different measurements. 

We know that

Scale factor = 5/2

If triangle ABC and DEF are similar

AB/DE = BC/EF = AC/DF = 5/2

Here

m∠a°=m∠d°

m∠b°=m∠e°

m∠c°=m∠f°

So we get

AC/DF = 5/2

Therefore, AC/DF = 5/2 is true.

These two scalene triangles are similar with a scale of 5:2. What is true about these figures?

Summary:

These two scalene triangles are similar with a scale of 5:2. AC/DF = 5/2 is true about these figures.
