no. the angles on all triangles add up to 180 deg.
not 171
No because the 3 interior angles of a triangle must add up to 180 degrees
No because the 4 interior angles of a quadrilateral add up to 360 degrees
Yes as for example a square has 4 interior equal angles of 90 degrees.
The sum of the measures of the angles in any triangle in the plane is 180 degrees. If two angles are 15 and 85 then their sum is 100 degrees and 180-100=80 degrees
Assuming that you mean 34, 45, and 100, no. The angles of a triangle need to add up to 180. You could have a triangle with angles of 35, 45, and 100.
A triangles angles have to add up to 180 degrees so since there are two angles that measure 40 it is 180-80=100(answer.)
125°
4
50 degrees (360 degrees in a quadrilateral)
80 degree
Exactly the same because they are both congruent
The missing angle measure is 100 degrees.
