It has 3 sides and 3 interior angles that add to 180 degrees
Its interior angles are an obtuse angle and 2 different acute angles
Its 3 exterior angles add up to 360 degrees
It has no diagonals
It has no lines of symmetry
It can tessellate
true
An obtuse isosceles triangle is a type of triangle that has two sides of equal length (isosceles) and one angle that is greater than 90 degrees (obtuse). This means that the triangle has one obtuse angle and two equal acute angles. The properties of an obtuse isosceles triangle include having a longer base opposite the obtuse angle and symmetrical characteristics along the axis that bisects the obtuse angle.
It means it has one angle over 90 degrees.
obtuse triangle
A triangle with 1 obtuse angle is called an obtuse triangle.
It has one obtuse angle. It must, therefore, have two acute angles.

This means that the triangle has one obtuse angle and two equal acute angles. The properties of an obtuse isosceles triangle include having a longer base opposite the obtuse angle and symmetrical characteristics along the axis that bisects the obtuse angle.
The basic property that one of its angles is obtuse. There are very many other properties that can be derived from this.
It means it has one angle over 90 degrees.
An obtuse triangle has an obtuse angle.
An oxymoron. An equilateral triangle cannot be obtuse; an obtuse triangle cannot be equilateral.
obtuse triangle
A triangle with 1 obtuse angle is called an obtuse triangle.
-- No right triangle, acute triangle, or equilateral triangle has an obtuse angle in it. -- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it .
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.
