Given the length of sides of the triangle:
• AB = 16
,
• BC = 20
,
• CA = 17
Let's list the angles in order from the largest to the smallest.
Let's first make a sketch of the triangle:
The angle which is opposite the largest side will be the largest angle.
The angle which is opposite the smallest side will be the smallest angle.
Thus, we have:
Largest angle = ∠A
Smaller angle = ∠B
Smallest angle = ∠C
Therefore, arranging the angles from the largest to the smallest, we have:
∠A, ∠B, ∠C.
• ANSWER:
A. ∠A, ∠B, ∠C
