The coordinates of ∆ABC are A(-3, 2), B(5, 8) & C(11, 0). Which type of triangle is ∆ABC? Select All that apply.

Given:

The coordinates of ∆ABC are A(-3, 2), B(5, 8) & C(11, 0).

To find:

The type of the given triangle.

Solution:

Distance formula:

Using the distance formula, we get

Similarly,

And,

Two sides of the triangle are equal, i.e., . So, the triangle is an isosceles triangle.

Sum of square of two smaller side is

Using the Pythagoras theorem, we can say that the given triangle is a right triangle.

Therefore, the correct options are B and F.

wouldn't that be 30km?

Step-by-step explanation:both sides are the same length right? so that means that if u are rounding to the nearest tenth it would be 30.
