an triangle having two equal sides is known as isosceles
There is no such thing as a regular isosceles triangle. The only regular triangle is an equilateral triangle. Having said that, any triangle will produce regular tessellation.
Isosceles mean having two sides of equal length.
Actually, it is called an isosceles triangle. In Greek, isosceles means having equal legs: an isosceles triangles has two sides (legs) of equal length.
isosceles ( having two equal sides)
Yes. An equilateral triangle is a triangle where all sides are equal and all angles are equal, therefore it meets the criteria of an isosceles triangle (having at least two sides that are equal).
It depends on the definition used. If you are defining an isosceles triangle as having exactly two sides of equal length, then no. If you define it as having at least two, then yes. An equilateral triangle has three lines of symmetry, but whether or not that counts as an isosceles triangle depends on the definition used. So, maybe.
When a triangle has 2 sides that are equal in length it is isosceles from Latin and Greek words. Isosceles may also be a mathematical geometric shape with at least 2 sides having the same length.
A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal. So an isosceles triangle is not an equilateral triangle because all sides are not equal.
An isosceles triangle.
Isosceles means having equal "legs". It can be a triangle, trapezium or a shape with more sides.
A triangle that has two sides of equal length. Sometimes it is specified as having two and only two sides of equal length, and sometimes as having at least two sides of equal length
