Every isosceles triangle. An equilateral triangle is a special case of an isoceles triangle
-- An isosceles triangle has two equal sides. -- An isosceles triangle has two equal angles. -- An isosceles triangle has two equal interior-angle bisectors. -- The bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the triangle's base.
Yes - if you define an equilateral triangle as one in which at least two sides are equal.
rectangle is the "special name" of a shape with 4 corners (square). triangles are split in 3 groups. right triangle, one corner is 90 degrees equilateral triangle, every corner is 60 degrees isosceles triangle, two sides have the same length
An equilateral triangle, by definition, has three sides of equal length. The definition for an isosceles triangle is that it must have two sides of equal length, the other side being free to have any length. Based on these two definitions, we can say that an equilateral triangle is a special case of the isosceles triangle, namely one where the third side is also equal to the other two sides.
Every isosceles triangle. An equilateral triangle is a special case of an isoceles triangle
It is any triangle - one with no special characteristic - like a right angle, or two equal sides, etc.
-- An isosceles triangle has two equal sides. -- An isosceles triangle has two equal angles. -- An isosceles triangle has two equal interior-angle bisectors. -- The bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the triangle's base.
Yes - if you define an equilateral triangle as one in which at least two sides are equal.
A right triangle has one right angle and two acute angles. Right triangles have a hypotenuse and also two legs. You can use the Pythagorean Theorem to find the hypotenuse, or the two legs of the right triangle, as long as you have the side lengths of the other two sides on the right triangle.
An isosceles triangle has two congruent sides, and An equilateral triangle is a special isosceles triangle in which all three sides are congruent.Therefore, all equilateral triangles are isosceles
A isosceles triangle can have two equal angles, but an equilateral triangle is actually a special isosceles triangle, so it could also have 3.
There are three sides and all internal angles add up to 180 degrees
It has one obtuse angle. It must, therefore, have two acute angles.

No, a triangle cannot be a rhombus. A triangle is a polygon with three sides, while a rhombus is a polygon with four sides of equal length. These two shapes have different properties and cannot be the same.
