Q: Find the measures of the sides of [Image] and classify the triangle by its sides.

[Image]
- equilateral (Use the Distance Formula to find the lengths of the sides. [Image] If [Image] or [Image] or [Image], then the triangle is isosceles. If [Image], then the triangle is equilateral. If neither of the above, the triangle is scalene.)
- isosceles (Use the Distance Formula to find the lengths of the sides. [Image] If [Image] or [Image] or [Image], then the triangle is isosceles. If [Image], then the triangle is equilateral. If neither of the above, the triangle is scalene.)
- scalene (Use the Distance Formula to find the lengths of the sides. [Image] If [Image] or [Image] or [Image], then the triangle is isosceles. If [Image], then the triangle is equilateral. If neither of the above, the triangle is scalene.)
- obtuse (Use the Distance Formula to find the lengths of the sides. [Image] If [Image] or [Image] or [Image], then the triangle is isosceles. If [Image], then the triangle is equilateral. If neither of the above, the triangle is scalene.)
A: scalene
