1 vertex less than a hexagon is a pentagon.
2 angles more than a triangle is a pentagon.
Heptagon
Polygon
pentagon
an isosceles triangle can have any vertex angle less than 180 and greater than 0, as long the other two angles are equal. an isosceles triangle with a vertex of 179 degrees would just have the other two angles be 0.5 degrees. A right triangle with matching angles (both 45 degrees) would be both a right triangle and isosceles triangle.
A triangle with all angles measuring less than 90 degrees?That's an 'acute' triangle.
An acute triangle
An acute triangle is one in which all interior angles are less than 90 degrees.
This would be an acute triangle. If all three angles are 60 degrees, then it is equiangular.
A hexagon or pentagon will have obtuse angles (greater than 90 degrees). A triangle has angles that are all less than 90 and a square has only 90.

MYou just described an equilateral triangle which is in fact isosceles and acute, and additional any isosceles triangle with a vertex angle of less than 90 is acute as the base angles are congruent and all three angles must add to180
This is a triangle in which all of the angles are less than 90°.
You are an irregular hexagon.
An acute triangle.
It is an acute triangle and if the acute angles are of different sizes then it is a scalene triangle.
A triangle with all angles measuring less than 90 degrees?That's an 'acute' triangle.
A triangle has fewer than 4 vertices.
More- each angle is over 90 degrees.
An Isosceles Triangle is a triangle with all angles less than 90o So there are no obtuse angles (between 90o to 180o).
An acute triangle has all angles less than 90o.
