# Identifying Triangles In Exercises 23-26, find the lengths of the sides of the triangle with the given vertices, and determine whether the triangle is a right triangle, an isosceles triangle, or neither.(-1, 0, -2), (-1, 5, 2), (-3, -1, 1)

To determine

To calculate: The sides of the triangle and also find that triangle is a right tringle, an isosceles triangle, or neither, if the vertices of the triangle is (1,0,2),(1,5,2) and (3,1,1).

Explanation

Given Information:

The vertices of the triangle, (1,0,2),(1,5,2) and (3,1,1).

Formula used:

Distance formula in space, the distance (d) between two points, (x1,y1,z1) and (x2,y2,z2) is defined as,

d=(x2x1)2+(y2y1)2+(z2z1)2

Calculation:

Let the vertices of the triangle, A=(1,0,2),B=(1,5,2) and C=(3,1,1).

To find the sides AB of the triangle by the use of distance formula,

AB=(1(1))2+(50)2+(2(2))2=0+25+16=
