An isosceles triangle has two equal angles.
A triangle that has three equal sides, and therefore three equal angles, is called an equilateral triangle.
There cannot be a triangle which has 2 equal sides and 3 equal angles. The number of sides and angles which are equal must be the same: 0, 2 or 3.
Isosceles
Size or internal angles?
It depends on what kind of triangle.
It is an equiangular triangle it is correct.
An isosceles triangle has two equal side and angle measurements.
Equilateral triangle
This is a scalene triangle: The sum of the angles of any triangle must be 180 degrees. Subtracting the given angles from 180 leaves 98 degrees for the third angle. Therefore, no two angles of the triangle are equal, and no two sides can be equal.
A triangle that has three equal sides, and therefore three equal angles, is called an equilateral triangle.
It is an equilateral triangle that has three equal 60 degree angles.
A triangle with three equal sides and angles is an equilateral triangle. It could also be called an equiangular triangle.
In a triangle, if all of the angles are 60 degrees, then all three sides of the triangle are equal to each other. Basically, if the angles are equal than the sides must be equal. This kind of triangle is called an equilateral triangle.
There cannot be a triangle which has 2 equal sides and 3 equal angles. The number of sides and angles which are equal must be the same: 0, 2 or 3.
An acute triangle.
It is a scalene triangle
