Solution:
Since this triangle has two 52° angles, it means that this triangle has two equivalent angles.
Equilateral triangle:
An equilateral triangle has:
- Three equal sides
- Three equal angles
The triangle we are looking for must have two equal angles. Since equilateral triangles have three equal angles, the triangle we are looking for is not an equilateral triangle.
Isosceles triangle:
An isosceles triangle has:
- Two equal sides
- Two equal angles
The triangle we are looking for must have two equivalent angles. Since an isosceles triangle must have two equivalent angles, the triangle we are looking for is an isosceles triangle.
Scalene triangle:
A scalene triangle has:
- All different sides
- All different angles
The triangle we are looking for must have two equivalent angles. Since a scalene triangle must have all different angles, the triangle we are looking for is not a scalene triangle.
