Best Answer

Sum of interior angles - 180 degree (each side 60 degree)

Sum of exterior angles of a polygon - 360 degree

More answers

Each pair of interior and interior is 180 deg so 3*180 = 540 deg

They are all 60 degrees.

All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.

The sum of all the interior angles of a triangle is 180 degrees while the sum of the exterior angles is 360. you can calculate for the measurements of the interior angles of a polygon by using the formula S=(n-2)(180) where n is the number of sides

The 3 interior angles of any triangle add up to 180 degrees and the 3 exterior angles add up to 360 degrees

The interior angles of a triangle all add up to 180 degrees.

That's not possible.Two interior angles of a triangle can't add up to 261Â°, because all three of the interior anglesin any triangle always add up to 180Â°.

The interior angles of a triangle all add up to 180 degrees.

360A triangle is a polygon with three sides and three angles. The sum of the interior angles of a polygon equals 180(n - 2), where n is the number of sides.180(3 - 2) = 180°Assuming all the angles in the triangle are congruent, find the measure of one interior angle.180° ÷ 3 = 60°If an interior angle equals 60°, then its corresponding exterior angle will equal 120° because the angles are supplementary (their sum is 180°).120° × 3 = 360°Therefore, the sum of the exterior angles of a triangle is 360°.study island

No, they are not always obtuse, because a scalene triangle can also sometimes be an obtuse triangle (meaning that one interior angle is obtuse), making one exterior angle acute. Scalene triangles also can be a right triangles (meaning that one interior angle is a right angle), which would make an exterior angle a right angle. Then also they can be acute triangles, in this case all 3 exterior angles are obtuse.

The easiest way to solve this is to use the exterior angles of the polygon. The sum of an exterior angle and interior angle is 180o. Also the sum of all the exterior angles of a polygon is 360o. As the polygon is regular, all the interior angles are the same and all the exterior angles are the same. So, for an interior angle of 172o the exterior angle is 180-172 = 8o. The sum of all the exterior angles is 360o so how many 8o make up 360o? 360/8=45. Thus the polygon with interior angles of 172o has 45 sides.

-- The sum of the four exterior angles is 360 degrees. -- The sum of the four interior angles is also 360 degrees. -- So the sum of all the interior and exterior angles is 720 degrees.

Each pair of exterior and interior angles sum to 180 degrees.The sum of all exterior angles of a polygon is 360 degrees.

No, the interior angles of a triangle measure 180° altogether.
