Answer:
isosceles triangle
Step-by-step explanation:
If a triangle has at least two equal sides, the triangle is referred to as the isosceles triangle. In the given diagram, it is shown that the two sides are equal. Moreover, this type of triangle has two equal angles.
The equilateral triangle means the triangle is having three equal sides but no right angle. A scalene triangle indicates the triangle has three different sides.
Finally, the obtuse triangle means the triangle has at least one obtuse angle. That means one side has more than 90 degrees.
