Answer:
The correct answer is C). congruent corresponding angles and proportional side lengths
Step-by-step explanation:
Similar Triangles : The two triangles are said to be similar to each other if their all corresponding angles are congruent to each other and the corresponding sides are proportional to each other.
Now, Given that two acute triangles are similar.
So, By using the definition of similarity of two triangles
We can conclude that :
All the corresponding angles of the acute triangles will be congruent to each other.
Also, The sides of both the acute triangles will be proportional to each other.
Therefore, The correct answer is C). congruent corresponding angles and proportional side lengths
