An isosceles triangle is not a regular triangle because it has 1 side that doesn't equal the other 2. For it to be a regular triangle it will need to have all sides the same length.
Here are the three types of triangle classification:
In a equilateral triangle or also known as regular triangle "all" sides must have the same length.
In an isosceles triangle "at least" two sides must have the same length.
In an scalene triangle all sides must be of different lengths
Therefor it can be said that a regular triangle is a type of isosceles triangle since it has at least 2 sides of the same length. But remember if one side changes length and 2 remain the same it becomes an isosceles, if all sides are of different lengths then it becomes scalene.

Is isosceles triangle regular?
No.
What is the difference between an isosceles and a regular triangle?
An isosceles triangle has two equal sides and one that isn't. A regular triangle has three equal sides.
Is a isosceles acute triangle a regular polygon?
A regular polygon is one which has all equal sides. But in an isosceles triangle, only 2 sides are equal. The third side has a different measure.Thus an isosceles acute triangle is not a regular polygon.
Will a regular isosceles triangle tessellate?
No, a regular isosceles triangle will not tessellate. In order for a shape to tessellate, it must be able to fit together with copies of itself without any gaps or overlaps. Regular isosceles triangles have angles of 90, 45, and 45 degrees, which do not allow for a repeating pattern that covers a plane without any spaces. Regular polygons that tessellate include equilateral triangles, squares, and hexagons.
Example of a non-regular polygon?
An isosceles triangle or a rhombus.
Is a isocels triangle a regular polygon?
A regular polygon is a shape in which all angles are equal. An isosceles triangle has two equal sides, thus two equal angles, but the other side/angle differs. Therefore an isosceles triangle is not a regular polygon.
Draw a triangle that is not a regular triangle?
If by regular, you're referring to a regular polygon which has all sides equal length, and all angles equal, then an equilateral triangle is a regular triangle. If you draw a scalene triangle or an isosceles triangle then it will not be equilateral.
Can an iscoceles have a 60 degrees angle?
Yes. In this case, the isosceles triangle would more specifically be an equilateral triangle - this can be considered a special case of an isosceles triangle.
If it is an equilateral triangle then it is an isosceles triangle?
Let us recall the definition of an isosceles triangle. An isosceles triangle is a triangle with two equal or congruent sides. In this definition, it is not stated that it has exactly two equal sides. An equilateral triangle has three equal or congruent sides. If it has three equal sides, then it must have two equal sides. Therefore, an equilateral triangle is considered as an isosceles triangle. But, an isosceles triangle is not necessarily an equilateral triangle.
Is a isosceles triangle a regular shape?
No although it has 2 equal sides
What is the length of the sides of an isosceles triangle?
The length of the sides of an isosceles triangle are not set in stone. An isosceles triangle is defined as a triangle with at least two congruent sides. Equilateral triangles; that is, triangles in which all sides are of equal length are also considered to be isosceles triangles. Therefore, as long as at least two sides of the triangle are congruent, (Of equal length) said triangle is an isosceles triangle.
How many sides of a triangle must be congruent to be considered an isosceles triangle?
2 sides
