Given the side lengths, determine if the triangle is acute, right, obtuse, or not a triangle

20,23,41

• not a triangle

• Acute

• Right

• Obtuse

Find the value of x.

• 80

• 95

• 110

• 145

Which set of angle measures could be the interior angles of a triangle?

• 25^o, 30^o, 35^o

• 35^o, 60^o, 75^o

• 45^o, 60^o, 75^o

• 60^o, 90^o, 120^o

Which equation could be used to find the value of x in the triangle.

• 13x + 11 = 180

• 29x + 6 = 180

• 10x + 90 = 180

How do you find what all the interior angles equal up too in a triangle when an interior angle is missing?

• Add them together

• Subtract the angles by 180 separately

• You add the angles given and subtract the sum by 180

• Subtract them by each other
