An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base

The base angles of an isosceles triangle are congruent.

The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.

Base Angles

It will be either isosceles or equilateral. It is equilateral if all of the angles are congruent.

It is an isosceles triangle

The base angles of an isosceles triangle are the two angles with the same measure, each formed by the intersection between the base of the triangle and one of the two legs.

No. It need not be the base angles that are equal, it can be one of the base angles and the top angle (if the triangle is tipped over). Also, the base angle are equal in an equilateral triangle - although an equilateral triangle is a special kind of isosceles triangle.
