A scalene triangle is irregular. Only an equilateral triangle is regular.
obtuse triangle
An obtuse triangle has an obtuse angle.
An oxymoron. An equilateral triangle cannot be obtuse; an obtuse triangle cannot be equilateral.
There are five different types of triangles named after their angles. Right triangle, Acute triangle, Isosceles Triangle ,equilateral triangle, and obtuse triangle. The Obtuse Triangle is the triangle with an obtuse angle.
Irregular
No because an equilateral triangle is a regular polygon whereas an obtuse triangle is irregular

A scalene triangle is irregular. Only an equilateral triangle is regular.
No.
No.
No - not a plane triangle. The angles of a regular triangle must be equal. So an obtuse triangle, if regular, would have three obtuse angles. The sum of the angles would then be greater than 3*90 = 270 degrees. But the sum of angles of a triangle must be 180 degrees.
irregular
It can be either
A triangle is only a regular triangle in the form of an equilateral triangle
No because an obtuse angle is greater than 90 degrees and a regular triangle is an equilateral triangle that has 3 equal 60 degree angles that add up to 180 degrees.
it is an irregular shape
