200
Can you form this triangle? Why or why not?
A triangle with sides:
5.5 ft, 11.8 ft, 13.2 ft
YES, because 5.5 + 11.8 > 13.2
200

Obtuse Isosceles
300
Can you form this triangle? Why or why not?
A triangle with angles:
40 degrees, 50 degrees, 90 degrees
Yes, because 40 + 50 + 90 = 180 degrees.
300

300
I am a triangle with a 104 degree angle and 3 different length sides.
Obtuse Scalene
400
Can you form this triangle? Why or why not?
A triangles with sides:
10 INCHES, 1 INCH, 12 INCHES
No, because 10 + 1 < 12
400

Equilateral or Equiangular
500
Can you form this triangle? Why or why not?
A triangle with sides:
2 ft, 4 ft, 6 ft
NO, because 2 + 4 = 6
500
What is the range of the length of the third side? Write your answer as an inequality.
