Understanding Suberect Triangles: Definition and Characteristics

Suberect is a term used in geometry to describe a type of triangle that has one angle greater than 90 degrees but less than 180 degrees. In other words, it is a triangle with a "sub-right" angle.

A suberect triangle is characterized by having one angle that is greater than 90 degrees and two angles that are less than 90 degrees. The sum of the interior angles of a suberect triangle is always greater than 180 degrees.

Here's an example of a suberect triangle:

In this triangle, angle A is greater than 90 degrees (let's say it's 100 degrees), and angles B and C are both less than 90 degrees (let's say they're 60 degrees and 70 degrees, respectively). The sum of the interior angles of this triangle is:

A + B + C = 100 + 60 + 70 = 230 degrees

As you can see, the sum of the interior angles of a suberect triangle is greater than 180 degrees, which is the defining characteristic of this type of triangle.
