OK. Done.
Now what ?
a triangle is not regular
No because a scalene triangle has no right angles
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.
Only when its an equilateral triangle then it is a regular polygon
no; a triangle must have an obtuse angle if one of its altitudes is outside of the triangle, and in this case 2 of the altitudes are out of the triangle.

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.
Yes it is possible
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.
A scalene triangle is irregular. Only an equilateral triangle is regular.
A triangle.
A regular triangle is a equalateral triangle. A regular triangle is one for which all sides are congruent and all interior angles ---- are congruent ---- ---- ---- ----

Then the students shouldtell her that you cannot have an teacher: the indefinite article would require it to be "a teacher" and,sketch and label the angles of a triangle as asked to do.
no; a triangle must have an obtuse angle if one of its altitudes is outside of the triangle, and in this case 2 of the altitudes are out of the triangle.
A triangle is only a regular triangle in the form of an equilateral triangle
