Three equal sides
Three equal angles, always 60°
Isosceles TriangleTwo equal sides
Two equal angles
Scalene TriangleNo equal sides
No equal angles
There are three special names given to triangles that tell how many sides (or angles) are equal.
There can be 3, 2 or no equal sides/angles:

What are two names for a triangle?
Two names for a triangle are "scalene triangle" and "isosceles triangle." A scalene triangle is a triangle with three unequal sides, while an isosceles triangle is a triangle with at least two equal sides. These names are based on the measurements of the sides of the triangle and help classify different types of triangles based on their properties.
Name a three corner shape other than a triangle?
Triangle means 3 angles. No other shape exists and any three angle shape is a triangle
What is a shape which has 3 lines but isn't a triangle?
If the shape has three straight lines and no other lines then it has to be a triangle
How do you classify a triangle by its angles?
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
What is a triangle with three sides called?
Since the question asks for sides, the answer would be an equilateral triangle. An equilateral triangle has three congruent sides.Of course, an equilateral triangle is also an equiangularone. All sides are the same length, so all three angles are 60° . Congruence is usually applied with respect to TWO triangles. If each triangle has three sides equal to the other triangle's three sides, then the triangles are congruent.equilateral
