Answer 1

To determine which types of triangles are possible based on the Triangle Inequality Theorem, we can analyze the options given:

1. Obtuse Equilateral: This is not possible. An equilateral triangle has all angles equal to 60 degrees, which is not obtuse.

2. Right Equilateral: This is also not possible. A right triangle has one angle of 90 degrees, while in an equilateral triangle all angles measure 60 degrees.

3. Right Isosceles: This is possible. A right isosceles triangle has one 90-degree angle and two 45-degree angles, fitting within the principles of the Triangle Inequality Theorem.

4. Equilateral Scalene: This is not possible. An equilateral triangle has all sides equal, while a scalene triangle has no equal sides.

Therefore, the type of triangle that is possible from the options provided is right isosceles.
