The interior angles of a triangle add up to 180 degrees.
The exterior angles of a triangle add up to 360 degrees.
A triangle has 3 interior angles that add up to 180 degrees and 3 exterior angles that add up to 360 degrees
The Interior angles of a triangle add up to 180° The Exterior angles of a triangle (or any other polygon) add up to 360°.
That's not possible.Two interior angles of a triangle can't add up to 261°, because all three of the interior anglesin any triangle always add up to 180°.
The 3 interior angles of this equilateral triangle will add up to 180 degrees
They don't. The interior angles of a triangle add up to 180°. The complements of each of these angles adds up to 360°. So 3 times 360 minus 180 = 900. This is your answer.
A triangle has 3 interior angles that add up to 180 degrees and 3 exterior angles that add up to 360 degrees
With a protractor remembering that interior angle and exterior angle add up to 180 degrees because angles on a straight line add up to 180 degrees. The 3 interior angles of any triangle add up to 180 degrees and their 3 exterior angles add up to 360 degrees.
The 3 exterior angles of any triangle add up to 360 degrees and the 3 interior angles add up to 180 degrees.
Interior angles add up to 180 degrees Exterior angles add up to 360 degrees
They are its exterior angles and the 3 exterior angles of a triangle add up to 360 degrees whereas its 3 interior angles add up to 180 degrees.
Interior angles add up to 180 degrees Exterior angles add up to 360 degrees
The Interior angles of a triangle add up to 180° The Exterior angles of a triangle (or any other polygon) add up to 360°.
A triangle is a closed area with 3 sides and 3 angles. The interior angles add up to 1800 and the exterior angles add up to 3600.
Use a protractor and you'll find that the 3 interior angles add up to 180 degrees and that the 3 exterior angles add up to 360 degrees
180 degrees minus interior angle = exterior angle and that the 3 exterior angles of a triangle add up to 360 degrees.
The 3 interior angles of any triangle add up to 180 degrees and the 3 exterior angles add up to 360 degrees
if you are talking about the triangle rule as in angles, the triangle rule is that all the interior ( on the inside) angles always add up to 180 degrees. The exterior (on the outside) angles always add up to 360 degrees
