A triangle is the 2D name of a certain shape. A triangle has three sides and, in the case of a right angled triangle, has an angle of 90 degrees in one corner. There are many other names depending on the angles used.
An isosceles triangle is a triangle with at least two equal sides. While there are no other names, an equilateral triangle has 3 equal sides so it is also an isosceles triangle
an equilateral triangle.
the equilateral triangle
If it were, there would be no need to have two different names for it. An isosceles triangle has two equal sides. An equilateral triangle has all three sides equal.
equilateral triangle, scalene triangle, and isoceles triangle Also, acute, obtuse, and right
Scalene Triangle
equilateral triangle
a scalene triangle.
The name of the point at which all of a triangle's angle bisectors converge is the incenter.
An equilateral triangle can also be called a "regular" triangle
A scalene triangle
Scalene triangle = All sides are different lengths Isosceles triangle = Two sides have the same length Equilateral triangle = All three sides are the same length
The name of a triangle is dependent on the type of angles within it. If it has a right angle it is called a right triangle, if it has an obtuse angle it is an obtuse triangle, and if all three sides are acute it is an acute triangle.
This triangle is called a scalene triangle. All its sides and angles are unequal.
It's called an equilateral triangle.
Any 'random' triangle is usually 'named' after the names of its angles - so that a triangle with angles A, B and C is generally referred to as "triangle ABC" - when this format is follwoed, then the sides will generally be named in lower-case letters which correspond to the angle they oppose - so that side 'a' is opposite angle A, and so on. The only other "names" for triangles are for the type of triangle in question, if all tghe sides are the same length then it is an "equilateral" triangle, if one of the sides is a right angle (measures 90 degrees) it is a "right" triangle (or a "right-angled" triangle). If one of the angles is greater than 90 degrees it is an "obtuse" triangle, and if all the angles are less than 90 degrees it is an "acute" triangle
