There are three special names given to triangles that tell how many sides (or angles) are equal. Also iSOSceles has two equal "Sides" joined by an "Odd" side.
It is irregular by virtue of the fact that, although opposite sides are equal in length, adjacent sides are not. Shape (b) is an isosceles triangle, and is irregular.
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in An isosceles triangle also has two angles of the same measure, namely the angles opposite to the two sides of the same length; this fact is the content.
Because an equilateral triangle is also isosceles, all triangles are either scalene or isosceles. But when people call a triangle isosceles, they're usually referring.
An irregular shape doesn't have equal sides or equal angles. For example, an equilateral triangle is a regular shape because all the sides are equal AND all the.
Isosceles triangle is a regular polygon if its base equals in length to its sides.
This property is equivalent to two angles of the triangle being equal. An isosceles triangle therefore has both two equal sides and two equal angles. The name.
