scalene triangle
A parallelogram.
An angle is a geometric figure formed by two rays (or line segments) that share a common endpoint called the vertex. When discussing a shape with three sides of different lengths, you are referring to a triangle, specifically a scalene triangle. In a scalene triangle, all three sides have different lengths, and consequently, all three angles are also different.
The shape you are describing is an isosceles right triangle. This triangle has one right angle (90 degrees) and two sides of equal length, known as the legs. The third side, called the hypotenuse, is opposite the right angle and is longer than the other two sides. This configuration creates a distinct geometric shape with specific properties related to angles and side lengths.
If a shape has four sides and you know that it has one right angle, yet you do not know anything else about the shape, then the most specific geometric term you can assign to the shape is "quadrilateral". Unless you know about the other angles and side lengths, nothing more can be said.
