4. Decide if the segment lengths form a triangle. If they do, Indicate whether the triangle is acute, right, or obtuse.

(a) 16, 30, 34? (b) 4, 5, 6?

(c) 7, 24, 26? (d) 14, 21, 36?

To see if line segments may form a triangle basically one must check if the sum of two sides are greater than the third.

a + b > c

a + c > b

b + c > a

a. can form a triangle

b. can form a triangle

c. can form a triangle

d. cannot form a triangle as 14 + 21 = 35 which is not greater than 36

a = right triangle with the right angle between 16 and 30

b = acute triangle

c = obtuse triangle with teh obtuse angle between 7 and 24
