Answer:

This is an obtuse isosceles triangle.

Explanation:

There are two classifications of triangles that we are dealing with:

  • acute OR obtuse
  • isosceles OR scalene OR equilateral

First, acute means that all of the triangle's angles are less than 90°. Obtuse means that one of the triangle's angles is greater than 90°.

Here, we can see that angle C is greater than 90°. Therefore, the triangle is obtuse.

A scalene triangle is one with 3 different side lengths. An isosceles triangle is one with 2 of the same side lengths. An equilateral triangle has all 3 side lengths the same.

Here, we can see that sides AC and BC are both the same length, but not the same length as AB. Therefore, the triangle is isosceles.
