A scalene triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures. However, the sum of all the interior angles is always equal to 180 degrees. Thus, it meets the angle sum property of the triangle.

There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or noequal sides/angles: How to remember?Alphabetically they go 3, 2, none: 1. Equilateral: "equal"-lateral (lateral means side) so they have all equal sides 2. Isosceles: means "equal legs", and we have two legs, right? Also iSOSceles...

The area is half of the base times height. 1. "b" is the distance along the base 2. "h" is the height (measured at right angles to the base) Area = ½ × b × h The formula works for all triangles. Note: a simpler way of writing the formula is bh/2 The base can be any side, Just be sure the "height" is measured at right angles to the "base": (Note: Yo...
A scalene triangle is defined as a three-sided polygon whose side lengths and angles are all different. To identify if a triangle is scalene, check whether it has any congruent sides or angles; if it does, it is not a scalene triangle; if it doesn't, it is a scalene triangle.
