Measure it or use trigonometry if the 'included' angle is given.
By adding the three sides.
-- Find the length of one side. -- Find the length of another side. -- Find the length of the remaining side. -- Add the three numbers. -- Their sum is the perimeter of the scalene triangle.
The dimensions of the scalene triangle could be 7 by 5 by 3 inches
There are at least 8 different "measures" that we can think of for any triangle: three sides, three angles, a perimeter, and an area. We can't guess which one you're looking for. A 'scalene' triangle is simply any triangle in which no two sides are the same length. That fact doesn't help us.
It is an obtuse scalene triangle.
An obtuse triangle is a triangle whos angle measure is greater than 180. The length of the sides of a scalene triangle are all different.
A scalene triangle is a triangle in which all three sides have different lengths. The difference between a scalene right triangle and a scalene obtuse triangle is that in the first one, we can find the measure length of the third side when we know the lengths of the two other sides, and in the second one we cannot.
Scalene or Acute triangle
It is a scalene triangle
The perimeter is the distance around the outside edge. It can be anything on a scalene triangle, there are no constraints except it must be bigger than zero. you can work out the area using the formula half the base times the perpendicular height. This works on all triangles
A scalene triangle's three sides are all unequal to each other. To draw a scalene triangle, one needs a ruler to measure the lines and make sure that none of the triangle's sides are equal to each other.
