Determine if the segment lengths form a triangle. if so, would the triangle be acute, right, or obtuse? 4.1, 8.2, 12.2
a. no, they do not form a triangle.
b. yes, they would form an acute triangle.
c. yes, they would form a right triangle.
d. yes, they would form an obtuse triangle

Three line segments can form a triangle if the length of the longest segment is greater than the sum of the lengths of the shorter segments.

 
They can form a triangle.

Now if c is the length of the longest side and a and b are the lengths of the shorter sides, then:
- if , the triangle is right
- if , the triangle is acute
- if , the triangle is obtuse


The triangle is obtuse.

The answer is D.
