They equal 180 degrees
No, complementary angles need to ADD and EQUAL 90 degrees. Supplementary angles need to ADD/EQUAL 180 degrees. They do not necessarily need to be adjacent to each other, they only have to add up... Complementary = 90, Supplementary = 180

The Interior angles of a triangle add up to 180° The Exterior angles of a triangle (or any other polygon) add up to 360°.
if you multiply 15 and 9 you get 145
number to add to 51 to equal 180 = 129180 - 51 = 129
86 + 67
145 subtracted by 180 = -35

Assuming the question was if an isosceles triangle have angles that add up to 180 degrees, then yes. All triangles have angles that add up to 180 degrees.
18 and 10 18 x 10 = 180 18 + 10 = 28
-9 and 20.
They equal 180 degrees
supplementary --- they add to 180
yes quadrilaterals equal 360, triangles equal 180. and shapes with five sides is 540. every time a new side is added add 180
The 3 interior angles of any triangle add up to 180 degrees
Yes the 3 interior angles of any triangle always add up to 180 degrees
