It is an equilateral triangle which in fact has three 60 degree angles
It is an isosceles right angle triangle.
A right triangle has a 90 degree angle in it. This is not to be confused with a wrong triangle, which has two 90 degree angles.
A triangle with a 90 degree angle and two 45 degree angles.
A triangle has only three angles and they sum to 180 degrees.
A triangle with two 45 degree angles must be a right triangle.

They have one 90 degree angle and two 45 degree angles
A triangle with a 90 degree angle and two 45 degree angles.
A triangle with two 45 degree angles would have one 90 degree angle.It would be a right triangle.Further Information:-It is an isosceles right angle triangle
An obtuse angled isosceles triangle.
A triangle has only three angles and they sum to 180 degrees.
It is not possible for any triangle to have two interior90-degree angles.
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.
