FLASHCARD QUESTION
Front
If one angle of a triangle is 95° and another is 85°, what is the measure of the third angle?
Back
The third angle is 180° - 95° - 85° = 0°, which is not possible. Therefore, the angles cannot form a triangle.

Which set of angles does NOT create a triangle?
Back
The angles 50°, 60°, and 40° do NOT create a triangle because their sum is 150°, which is less than 180°.
