Nothing. A triangle is defined as a planar figure constructed with three line segments joined at their ends. A triangle has exactly three sides. Anything else is not a triangle.
An isosceles triangle has no parallel sides but it does have 2 sides of equal lengths
A triangle.
i don't get the joke. kidding. an equilateral triangle
It is simply a right angle triangle but if the sides were the same then it is an isoceles right angle 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 ---- ---- ---- ----
A scalene triangle has zero equal sides.
An isosceles triangle has no parallel sides but it does have 2 sides of equal lengths
A triangle.
If all three sides of a triangle have the same length, we call that triangle an "equilateral triangle".
zero
zero
An equilateral triangle.
scalene triangle
An equilateral triangle
It is an isosceles triangle that has two equal sides
A quadrilateral triangle is an oxymoron.A quadrilateral has four sides, a triangle has three so a quadrilateral triangle cannot exist. You could therefore say that it has zero sides.
When all three sides of a triangle are congruent, it is called an equilateral triangle.
