They are not all the same because obtuse angles vary from 90 degree angles to 180 degree angles.
NO!
Yes, all obtuse triangles are similar if they have the same angles. This is because similarity in triangles depends on the corresponding angles being equal. However, obtuse triangles can vary in size, so while they can be similar, not all obtuse triangles are similar unless their angles are exactly the same.
It is a parallelogram and if all 4 sides are equal then it is a rhombus
The interior angles of any regular pentagon, no matter the size, are all obtuse.
No there are different angle such as right angles, obtuse angles, and acute angles.
A parallelogram. A rhombus (a special case of parallelogram, with all 4 sides equal length) also fits this criteria.
First of all it is 'obtuse' because one of the angles is greater than 90 degrees. Secondly it is a ' scalene' because all the angles are of different size, this will make all the sides of different size. So the the triangle is an 'Obtuse Scalene Triangle'.
If by equilangular you mean all angles are the same, then no - the sum of the angles of a triangle must be 180o, so if all 3 are the same they must each be 60o and the triangle is called equilateral. However, an obtuse isosceles triangle is possible as the equal angles are the other two angles to the obtuse angle.
No if one angle is obtuse then they can't all be obtuse
There are no angles they are all obtuse angles
Yes. It must have an obtuse angle.
A regular hexagon has all angles obtuse.
