Will the following side lengths make a triangle? Explain your answer.
3 feet, 4 feet, 8 feet
No, because when you add the two smallest sides together they are less than the biggest side (3 + 4 = 7, and 7 is less than 8)

Ms. Latouche drew a triangle. What is the measure of the last angle?
78 degrees
200
Solve for the circumference of the circle shown.
31.4 ft

25.12 feet
300
Can the following angle measurements make a triangle? Explain why or why not.
12 degrees, 85 degrees, 20 degrees
No, because the sum of the angles is not 180 degrees.

A triangle has one angle that is 20 degrees, one side length that is 4 meters, and another side length that is 6 meters long. Is it possible to make two DIFFERENT triangles with these measurements, or is this a unique triangle? Draw the triangles to prove your answer.
Possible to make different triangles depending on the position of angles nad side lengths.
