An isosceles triangle has two equal sides and two equal angles
If you are talking about the triangle:An isosceles triangle has two sides of equal length. Sometimes it is specified as having two and only two sides of equal length, and sometimes as having at least two sides of equal length.If you are talking about the trapezoid (or trapezium):In Euclidean geometry, an isosceles trapezoid is a convex quadrilateral with the line of symmetry bisecting one pair of opposite sides.
A triangle.
A scalene triangle has three unequal sides, an equilateral triangle has three equal sides. An isosceles triangle has two equal sides. Because with a scalene triangle only two sides are equal but with a equilateral triangle that would mean all sides are equal. (scalene = 2 sides & equilateral = all sides equal)

If you mean can a triangle have 3 equal sides and the answer is yes it can and it is called an equilateral triangle.

equilateral means equal sides example equilateral triangle means triangle with all sides equal.

If you mean what shape has 3 sides, it's a triangle.
I guess you mean with ALL sides the same size it's an equilateral triangle
If you mean EQUAL sides and angles, than an equilateral triangle.
Do you mean an equilateral triangle? Then it is a triangle that has three equal sides and three equal interior angles.
if you mean ALL sides equal then no, because for a triangle to have ALL equal sides all angles must be equal (60 degrees), and an obtuse triangle must have an angle with 91 or more degrees. but if you mean TWO sides equal then yes. for example, a triangle with angles 40, 40 & 100 degrees would have two equal sides.
