• To understand the history of triangles

• To calculate the perimeter of triangles

What is the sum of the angles in any triangle?

• 270 degrees

• 360 degrees

• 180 degrees

• 90 degrees

If two angles in a triangle are 70 degrees and 35 degrees, what is the third angle?

• 105 degrees

• 95 degrees

• 85 degrees

• 75 degrees

What is an isosceles triangle?

• A triangle with all sides equal

• A triangle with all angles equal

• A triangle with two sides equal

In an isosceles triangle, if one angle is 68 degrees, what is the measure of the other angle opposite the equal side?

• 68 degrees

• 80 degrees

How do you find the missing angle in an isosceles triangle if two angles are known?

• Add the two angles and subtract from 360

• Divide the two angles

• Multiply the two angles

• Add the two angles and subtract from 180

What does the exterior angle theorem state?

• The exterior angle is equal to the sum of the two adjacent interior angles

• The exterior angle is equal to the sum of all interior angles

• The exterior angle is equal to the difference of the two opposite interior angles

• The exterior angle is equal to the sum of the two opposite interior angles

If one exterior angle of a triangle is 80 degrees and one interior angle is 39 degrees, what is the measure of the other interior angle?

• 101 degrees

• 41 degrees

• 61 degrees

• 127 degrees

How do you calculate an exterior angle in a triangle?

• Divide the two opposite interior angles

• Subtract the interior angle from 180

• Add the two opposite interior angles

• Multiply the two opposite interior angles

What is a linear pair of angles?

• Two angles that add up to 90 degrees

• Two angles that add up to 180 degrees

• Two angles that are equal

• Two angles that are complementary
