A triangle has vertices on a coordinate grid at A(-8, -10), B(9, -10), andC(9,-3). What is the length, in units, of AB?

Answers

The length of line AB is 17 units which is one side of a triangle.

What is a triangle?

A triangle is a closed 2D figure formed by joining three non-co-linear points. By the property of sides, triangles are of three types they are:- Equilateral triangle, Isosceles triangle, and scalene triangle.

We know the length of two given pairs of points can be determined by the distance formula which is \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2.

Given are the points of the vertices of a ΔABC are A(-8, -10), B(9, -10), and

C(9,-3).

∴ The length of line AB is,

= √((9 + 8)^2 + ( -10 + 10)^2) units.

= √(17^2) units.

= 17 units.
