Question

A triangle has vertices on the coordinate grid at points D (3, -3), E (0,2), and F (-1,-3)

Answer 1

4 units

Explanation:

A triangle has vertices on the coordinate grid at points D (3, -3), E (0, 2), and F (-1, -3). What is the length, in units, of DF ?

A triangle is a polygon with three sides and three angles.

The distance between two points
`(x_1,y_1)\ and\ (x_2,y_2)` on the coordinate plane is given by:

`Distance=√((x_2-x_1)^2+(y_2-y_1)^2)`

Given A triangle with vertices at points D (3, -3), E (0, 2), and F (-1, -3). The length of side DF is given as:

`DF=√((-1-3)^2+(-3-(-3))^2)=4\ units`
