1.15.21
(u) (8, 1), (k, - 4),(2-5
1.
(i) (7,-2), (5, 1), (3, k)
In each of the following find the value of 'k', for which the points are collin
triangle formed by joining the mid-points of the sides​

Answer 1

Step-by-step explanation:

$\frac{7}{1} = \frac{5}{1} = \frac{3}{k} \\ \frac{5}{1} = \frac{3}{k} \\ k = \frac{3}{5}$

Answer 2

Step-by-step explanation:

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
