Answer 2

Answer:

The given measurements has confirmed that the given triangle is a scalene triangle.

Given:

The sides of a triangle measure 12 cm, 8 cm and 20 cm

To find:

Kind of a triangle will be formed.

Solution:

Since the sides are of different length,

For an obtuse triangle, $Longest side^2$ > $other side^2 + other side^2$

$20^2 > 12^2 + 8^2$

400 > 144 + 64

400 > 208

Sides which have different lengths, they are called as scalene.
