A scalene triangle is a triangle that has no sides congruent sides. In other words, if all three sides of a triangle have different lengths, then we say that the triangle is a scalene triangle.

Take a look at the triangle I attached below.

It's a scalene triangle.

Answer:

A scalene triangle is a triangle whose sides are all different in length.

Example:

A triangle with side lengths 2cm, 4cm, and 6cm.

I have provided a visual example below.

Hope this helps :)

The area of a regular octagon is 35 cm 2 what is the area of a regular octagon with sides three times as large

Maurinko [17]

The area of a polygon = n*side^2 / (4 * tan(180/n))
where "n" is the number of sides

Let's calculate area for side = 2
area = 8*2^2 / (4 * tan(180/8))
area = 32 / (4 * tan(22.5))
area = 32 / 4*0.41421
 area = 19.3138746047 

Now, let's calculate area for side = 6
area = 8*6^2 / (4 * tan(180/8))
area = 288 / 1.65684 
area = 173.824871442 

 173.824871442 / 19.3138746047 = 9

So, the area would be 9 times larger.

ALSO, looking at the formula
n*side^2 / (4 * tan(180/n))
we can see that the side length appears just once in the formula and we are to square it in the calculation. So, if we increase the side length is increased by 3, then the area increases by 3^2 or 9.
