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

The 3rd angle of the triangle could be 90 degrees because the 3 angles in a triangle add up to 180 degrees.
The supplementary angle of the triangle.
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

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

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.
