Answer:
This is an obtuse isosceles triangle.
Explanation:
There are two classifications of triangles that we are dealing with:
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.
