The question probably refers to the internal angles of a triangle which total 180° .
Also, the angle at the centre of a circle and subtended by half the circle is 180°.
When there are 3 sided polygons like triangle the sum is always 180 degrees more the number of sides increase the more the sum of the angles like for quadrilateral = 360 degrees and for 5 sided polygons like pentagons we have it as 540* the formula is {180 - (360 / n)} x n where 'n' are the number of sides proof say triangle sum of angles => {180 - (360 / 3)} x 3 == 180 degrees which is clearly correct
SUPPLEMENTARY ANGLES are two angles the sum of whose measures is 180 degrees.
Supplementary angles have a sum of 180 degrees.
Supplementary
Supplementary angles add up to 180 degrees

No. Sum of measures of complimentary angles is 90 degrees.
180 degrees
supplementary angles
No. Only the sum of the measures of the angles of a triangle equal to 180 degrees; in the case of a quadrilateral it amounts to 360 degrees.
They are supplementary angles that add up to 180 degrees
