No. Some have all three sides the same, some have two and in some they are all different.
They are not - if you consider congruent triangles to be the same.
Only if they are congruent triangles
Yes- but not all isosceles triangles are right triangles. Isosceles means that two sides are the same length, and two angles are the same.
180 degrees, same as all triangles
yes. When you are finding the area of a triangle you do the same for all types of triangles.
Yes, all triangles have the sum of their angles as 180 degrees.
Congruent triangles are the same because all three sides measure the same length.
They are triangles all of whose sides are of the same length.
Acute triangles have angles less than 90 degrees. Right triangles have 90 degree angles.
NO they are not they all have the same measure but are not all comgruent
No. For example the triangles with sides {3, 4, 5} and {6, 8, 10} are similar but not congruent.
Scalene triangles. All three are different: Scalene Two are the same: Isosceles All three are the same: Equilateral
