The given vertices when plotted on the Cartesian plane will form a right angle triangle and so therefore its largest angle is 90 degrees.

If you mean vertices of: (-1, -1) (-1, 3) and (5, -1) then when plotted on the Cartesian plane it will form a right angle triangle with a base of 6 units and a height of 4 units. Area of triangle: 0.5*6*4 = 12 square units

If you mean vertices of (-4, 2) (-4, 5) and (3, 2) then it will form a right angle triangle when plotted on the Cartesian plane with sides of 3 units by 7 units by square root of 58 or about 7.616 units which is its hypotenuse and longest side

One - the section of the plane in which it lies.

That depends on where the triangle ABC is located on the Cartesian plane for the coordinates of its vertices to be determined.

An isosceles triangle and an equilateral triangle

By plotting the given vertices and then joining them together on the Cartesian plane the shape of a isosceles triangle will be formed with an area of 78 square units.

It appears to be an isosceles triangle when plotted on the Cartesian plane

If the vertices are at (0, -2) (8, -2) and (9, 1) on the Cartesian plane plane then by using the distance formulae and trigonometry the area of the triangle works out as 12 square units.
