Yes the sum of the 3 angles in a triangle is 180 degrees. For any regular polygon with n sides
the sum of the interior angles is (n-2)180. In this case n=3 so (3-2)(180)=180

The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
The sum of the angles should equal 180
The sum of the three interior angles in a triangle is always 180 degrees. If two angles in a triangle add up to 125 degrees, subtracting this sum from 180 gives you the measure of the third angle. Therefore, the third angle would be 180 - 125 = 55 degrees.
a triangle can have only one right angle because the sum of all the three angles of a triangle has to be 180. so if there are more than one right angles, the sum of the angles will exceed 180 and hence the plane figure will no longer be a triangle
A triangle can have one obtuse angle and two acute angles. The sum of all three angles must equal 180 degrees.
