The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
A triangle with all angles congruent are called equilateral. Each angle is 60 degrees.
The two "base" angles.
A scalene triangle can have an obtuse angle and two different acute angles.

The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
A triangle with all angles congruent are called equilateral. Each angle is 60 degrees.
If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
This are called congruent angles. For example, In an isosceles triangle, the two angles which are opposite to the sides that have the same length, have the same measurements. They are called the base angles of the triangle. When each of them is 45 degree, the triangle is also a right triangle, since the other angle is 90 degree.
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.

No
Two angles with equal measurements are called congruent angles.
Assuming you are referring to a triangle and are asking for one of the interior angle's measurements, this is the answer.Because it is an equilateral triangle, the measures of the 3 angles are the same. They add up to 180 by the interior angles theorem.Thus, the measure is 60 for each angle.
The Angle Side Angle postulate( ASA) states that if two angles and the included angle of one triangle are congruent to two angles and the included side of another triangle, then these two triangles are congruent.
The two angle bisectors of a triangle are congruent the those two angles are congruent. The angles are bisected the same meaning that the whole and half angle are the same. For example if they are bisected at the whole angle 50 each, then each half is 25. The bisectors really don't mean anything and all you need is 50 to know it's isosceles. 50 and 50 is 100 and the left over for the last angle is 80 adding to 180. AND overall any 2 congruent angles in a triangle have the same congruent legs making it isosceles.
