Best Answer

No!

A triangle has three points on it, and the sum of the exterior angles will always be greater than 180 degrees.

As a simple test, draw three dots in a triangle form, and join them up. Using a protractor, add the angles. This will be more 190degrees.

If you now place three dots in a straight line labelling them dots a, b, and c, and now join them up. The angle from the line between dots a-b, to the line between dots b-3 is 180degrees.

A right triangle has one exterior angle that's 90 degrees. No other kind of triangle has. All three of the triangle's exterior angles always add up to 360 degrees.

Interior angle+exterior angle = 180 degrees

Each exterior angle measures 120 degrees

It is the regular equilateral triangle whose each exterior angle is 120 degrees

They are all 60 degrees.

A right triangle has one exterior angle that's 90 degrees. No other kind of triangle has. All three of the triangle's exterior angles always add up to 360 degrees.

The sum of the exterior angles of a triangle is always 360 degrees. Therefore, each exterior angle of a triangle measures 120 degrees.

No :) Because one angle of the triangle is always acute and so the exterior has to be obtuse.

Interior angle+exterior angle = 180 degrees

Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle

It is the equilateral triangle that has the largest exterior angle of 120 degrees

Each exterior angle measures 120 degrees

It is the regular equilateral triangle whose each exterior angle is 120 degrees

180 degrees minus interior angle = exterior angle and that the 3 exterior angles of a triangle add up to 360 degrees.

They are all 60 degrees.

20 degrees

An exterior angle of a triangle can have a value between (but not including) 0 to 180 degrees.
