The correct answer is option (B)Yes, such a triangle is obtuse.
Properties of Triangle
Three important points:
- There is a special property of triangle that states that sum of all the angles in a triangle is 180°.
- if any angle in a triangle is more than 90°, then such a triangle is obtuse.
- if any two angles in a triangle are equal, then such a triangle is isosceles.
So here it is stated that one of the angles is 179°, therefore triangle is obtuse.
Now from first point the rest two angles has sum 1°,which does not necessarily mean that they are equal angles, therefore it is not necessarily isosceles triangle.
Therefore from above two conclusions, Option (B) is correct answer.
