they all have three sides, three angles, and the sum of their angles is always 180 degrees.
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.
similar triangles have all the same angles in each of them, and their sides can be of any length
No.
hi
NO! Only REGULAR Pentagons. All equilateral triangles are similar!!!
No not all obtuse triangular are similar. :)

Only right triangles.
Yes.

90 degree triangles are always similar.

Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other.When two triangles have corresponding sides with identical ratios, the triangles are similar.Of course if triangles are congruent, they are also similar.
