If you meant right angle then yes
Two sides of an isosceles triangle are equal. The base is the other side.
If it has 2 equal acute angles and 1 obtuse angle then it is an isosceles triangle.
An isosceles triangle is a right triangle only when the other two interior angles are each 45o.
An isosceles triangle is a triangle with at least two equal sides. While there are no other names, an equilateral triangle has 3 equal sides so it is also an isosceles triangle
The unequal side of an isosceles triangle is called the base.
It can be similar to each other with the base angles theorem. It would be 90 degrees and on the bottom would be both 45 degrees and if you would turn it sideways, there is your right triangle.
It would look similar to an isosceles triangle.
