CLASSIFYING THE TYPES OF TRIANGLES WITH COORDINATES WORKSHEET

Use the distance formula to classify triangle ABC, as either equilateral, isosceles or scalene :

Problem 1 :

A(3, -1), B(1, 8), C(-6, 1)

Solution

Problem 2 :

A(1, 0), B(3, 1), C(4, 5)

Solution

Problem 3 :

A(-1, 0), B(2, -2), C(4, 1)

Solution

Problem 4 :

A(√2, 0), B(-√2, 0), C(0, -√5)

Solution

Problem 5 :

A(√3, 1), B(-√3, 1), C(0, -2)

Solution

Problem 6 :

A(a, b), B(-a, b), C(0, 2)

Solution

Answer Key

1) It is isosceles triangle.
