Finding Exterior Angles of Triangles

If one angle in a triangle is 26 degrees and another is 90 degrees, what is the measure of the third angle?

• 84 degrees

• 74 degrees

• 64 degrees

• 54 degrees

What is the sum of all interior angles in a triangle?

• 360 degrees

• 270 degrees

• 180 degrees

• 90 degrees

What do we call the angle formed outside a triangle when one side is extended?

• Interior angle

• Remote angle

• Exterior angle

• Supplementary angle

Which angles are referred to as remote interior angles?

• Angles adjacent to the exterior angle

• Angles opposite to the exterior angle

• Angles forming a straight line

• Angles inside the triangle

What is the relationship between an exterior angle and the remote interior angles?

• They are supplementary

• They form a right angle

• They are equal

• The exterior angle is the sum of the remote interior angles

If the remote interior angles are 68 degrees and 42 degrees, what is the measure of the exterior angle?

• 100 degrees

• 130 degrees

• 110 degrees

• 120 degrees

If an exterior angle is 110 degrees, what is the measure of the adjacent interior angle?

• 60 degrees

• 70 degrees

• 90 degrees

• 80 degrees

Given the equation 7x + 7 = 4x + 4 + 4x - 9, what is the value of x?

If x = 12, what is the measure of the exterior angle 7x + 7?

• 84 degrees

• 91 degrees

• 105 degrees

• 98 degrees

If the exterior angle is 91 degrees, what is the measure of the adjacent interior angle?
