Question

Check whether (𝟓, −𝟐), (𝟔, 𝟒) and (𝟕, −𝟐) are the vertices of
an isosceles triangle.

Answer 1

• An isosceles triangle has two equal sides. use the distance formula to verify that.
• Let the coordinates be A(5, -2) , B(6, 4), and C(7, -2).

• Now that AB = BC, A, B, and C form the vertices of the isosceles triangle.
