i know it has a flat edged name curved bottom and a name for both is tripor

105 degrees
The 3rd angle of the triangle could be 90 degrees because the 3 angles in a triangle add up to 180 degrees.
draw a triangle & its exterior angle on one side and name he exterior angle as4 and interior opp. angle as 1 and 2 and name the third angle as 3 now we know exterior angle is equal to the sum of interior opp. angle so,angle1+angle2=angle 4 we also know angle3+angle4=180(linear pair) NOW from this 2 equation angle1+angle2+angle3=180
The supplementary angle of the triangle.

107 because the overall sum of exterior angles add up to 360

The supplementary angle of the triangle.
Exterior angle of any plane figure total 360 degrees, so 360 - (110 + 100) ie 360 - 210 = 150
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
Two angles of a triangle add up to 65°. What is the measure of the third angle?
The third angle of an isosceles triangle doesn't have a name.
The third angle is 30 degrees and it is an isosceles triangle.
