A triangle with 3 equal sides and angles.
an angle that forms a linear pair with one of the interior angles of the triangle.
A closed figure having three sides and three angles
Pythagoras' theorem states that for any right angle triangle its hypotenuse when squared is equal to the sum of its squared sides.
Triangle
It is a 3 sided triangle with different side lengths and 3 interior angles of different sizes.
No.The definition of an oblique triangle is "any triangle that is not a right triangle".
No. An isosceles triangle has, by definition, two sides of equal length. A scalene triangle has, by definition, no sides of equal length. So, by definition (and the fact that 0 is not 2), an isosceles triangle cannot be scalene.
a triangle with one right angle
A triangle, by definition, can have only three sides. So a four sided triangle simply cannot exist!A triangle, by definition, can have only three sides.

By definition, a triangle has three sides.
a triangle that contains an obtuse interior angle
A triangle with 3 equal sides and angles.
Absolutely false. A scalene triangle by definition has no side equal to another. An isosceles triangle by definition has two equal sides.
There is no formal definition: it is any side of a triangle. Often, if the triangle has a horizontal base, then it is one of the sloped sides. In a right angled triangle, it is one of sides adjacent to the right angle. In an isosceles triangle, it is one of the equal sides.
isosceles triangle is a 3-sides triangle
No it cannot. A triangle is by definition a three sided shape.
