No but its apex angle can be a right angle with 2 equal base angles of 45 degrees
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
It usually is a right angle that represents an isosceles triangle but there are some cases that the right and left side are equal and the base is the one with an unequal length.
In an isosceles triangle, the altitude from the vertex angle to the base bisects the base and is also the median, as it divides the triangle into two congruent right triangles. This altitude is perpendicular to the base, creating two equal segments. Consequently, in an isosceles triangle, the altitude, median, and angle bisector from the vertex angle to the base are all the same line segment.
Yes and it will have a 90 degree angle and two angles of 45 degrees. Such a triangle is called an isosceles right angle triangle.
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.

The third angle of an isosceles triangle doesn't have a name.

90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
The angle that is not congruent to the base angles of an isosceles triangle is called the "vertex angle." In an isosceles triangle, the vertex angle is formed by the two equal sides, while the base angles are the angles opposite the equal sides.
In an isosceles triangle, two angles, and therefore sides (Base Angle Theorem), are congruent. This does not mean that all isosceles triangles are also right triangles - there is only one (45, 45, 90 triangle).
Because it has 2 equal base angles and 2 equal sides It is the only triangle that is both an isosceles and right angle triangle
Vertex angle
O
-- An isosceles triangle has two equal sides. -- An isosceles triangle has two equal angles. -- An isosceles triangle has two equal interior-angle bisectors. -- The bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the triangle's base.
