an isosceles triangle
It is called an isosceles triangle.
An equilateral triangle can't be a right triangle since an equilateral triangle has all 60° angles, which are NOT right angles [measuring 90°]. If a triangle is a right triangle, then it has a right angle!
A scalene triangle is one in which all angles are different and all sides are different. An isosceles triangle has two angles the same and two sides the same. An equilateral triangle has all three angles the same (60o) and all three sides the same. A right angle triangle has one of the angles 90o; the side opposite the right angle (90o) is called the hypotenuse.
A triangle with no angles is called a degenerate triangle. It occurs when the three vertices are collinear, meaning they all lie on the same straight line. In a degenerate triangle, the side lengths sum up to zero.
Equilateral triangle
A scalene triangle.
Not only are all three angles the same, the sides are too.It's called an equilateral triangle.
an isosceles triangle
It is called an isosceles triangle.
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.

It is an isosceles triangle and the other 2 angles will each measure 40 degrees
Equilateral and acute
In an isosceles triangle, two of the angles are the same.
