Scalene Triangle. No equal sides. No equal angles. How to remember? Alphabetically they go 3, 2, none: Equilateral: "equal" -lateral (lateral means side) so they have all equal sides. Isosceles: means "equal legs", and we have two legs, right? Also i SOS celes has two equal "S ides" joined by an " O dd" side.
An isosceles triangle is a type of triangle that has any two sides equal in length. The two angles of an isosceles triangle, opposite to equal sides, are equal in measure. In geometry, triangle is a three-sided polygon that is classified into three categories based on its sides, such as: Scalene triangle (All three sides are unequal) Isosceles ...

- An isosceles triangle is a triangle with two equal sides. Also, the angles opposite to the two equal sides are also congruent.
- Depends on the angles between the two legs of a triangle, the isosceles triangle is classified as: Isosceles acute triangle Isosceles right trian...
- The area of the isosceles triangle is defined as half the product of base and height of a triangle. The formula to calculate the area of an isoscel...
- Since the isosceles triangle has two equal sides, the formula to calculate the perimeter is 2a+b units, where “a” is the length of two equal legs a...
- The angles opposite to the two equal sides of a triangle are also equal. The two equal sides of an isosceles triangle are called the legs and the...

- Equilateral triangle. The Equilateral triangle shown on the left has three congruent sides and three congruent angles. Each angle is 60°.
- Isosceles triangle. The Isosceles triangle shown on the left has two equal sides and two equal angles.
- Scalene Triangle. The Scalene Triangle has no congruent sides. In other words, each side must have a different length.
In geometry, an isosceles triangle (/ aɪ ˈ s ɒ s ə l iː z /) is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
Isosceles triangle. An isosceles triangle is a triangle that has at least two sides of equal length. Since the sides of a triangle correspond to its angles, this means that isosceles triangles also have two angles of equal measure. The figure below shows an isosceles triangle example. The tally marks on the sides of the triangle indicate the ...
A scalene triangle is one in which all three sides and all three angles are of different measurements, an equilateral triangle is one with all three sides and angles equal, and in an isosceles triangle, two sides and two angles are equal in measurement. Observe the table given below to understand the differences and similarities in scalene, equilateral, and isosceles triangles.
