Answer:
Isosceles triangle
Step-by-step explanation:
There are three different kinds of triangle: equilateral, isosceles, and scalene.
-Equilateral triangles are triangles where all 3 sides and angles are the same. (First image)
-Isosceles triangles are triangles where 2 of the sides and angles are the same, while the third side and angle is different. (Second image)
-Scalene triangles are triangles where all 3 sides and angles are different. (Third image)
In the case of this triangle, two of the sides have the same 52 degree angle. They would also have the same side lengths, and <u>thus be a isosceles triangle. </u>
Hope this helps! :3
