It seems like you may be asking about a specific triangle, but I need more context to assist you properly. If you're referring to a triangle in geometry, there are several kinds of right triangles, such as:
- Right Isosceles Triangle - A right triangle with two equal sides.
- 30-60-90 Triangle - A right triangle with angles of 30, 60, and 90 degrees.
- 45-45-90 Triangle - A right triangle with two 45-degree angles.
If you have a specific triangle in mind or if there is a visual reference or a specific characteristic you'd like to describe, please provide more details!
