No.
An isosceles triangle has two equal sides and one that isn't. A regular triangle has three equal sides.
Irregular
It can be either
Yes and no. Being irregular means that all sides and angles are different, thus, giving the shape no symmetry. Regular is just the opposite, of course. Triangles can be both because there can be different kinds of triangles. For example, an equilateral triangle would be regular because all its sides and angles are equal. Now a scalene triangle is different, for none of its sides are equal. Though, there is another triangle, called the isosceles triangle, that only has two of its sides equal. Remember, an irregular shape must have all its sides and angles to be unmatched, so that means the isosceles is still regular.
it is irregularIt is irregular although it has two equal sides
It is irregular as not all the sides have the same length.
A scalene triangle is irregular. Only an equilateral triangle is regular.
No.
An isosceles triangle has two equal sides and one that isn't. A regular triangle has three equal sides.
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.

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.

A triangle is only a regular triangle in the form of an equilateral triangle
