Answer:
ABC is an isosceles triangle.
Explanation:
Given,
The triangle ABC has vertices at A(2 , 2), B(4, 7), and C(6, 2).
By the distance formula,









Since, AB = BC ≠ CA
⇒ ABC is not an equilateral triangle,
AB = BC ⇒ ABC is an isosceles triangle.
⇒ ABC is not a scalene triangle.
AB² + BC² ≠ CA² or AB² + CA² ≠ BC² or CA² + BC² ≠ AB²
⇒ ABC is not a right triangle,
