Question

Can you draw a triangle with the vertices (1,5),(5,8)and(13,14)?​

Answer 1

Answer:

the triangle cannot be formed  

Step-by-step explanation:

area of triangle = $1/2$$[x_1y_2 +x_2y_3 + x_3y_1] - [x_2y_1+x_3y_2+x_1y_3]$

                          = 1/2 {[8+70+65] - {25+104+14}]

                           = 1/2[{143} - {143}]

                           = 1/2 [0]

                          = 0  

since the area is zero the triangle cannot be formed

Answer 2

Answer:

A,B and C are collinear.Hence we cannot draw triangle using these coordinates
