All triangles are unique compared to other polygons inasmuch that they have only 3 sides and no diagonals.
Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.
No. But all isosceles triangles and equilateral triangles are.
If one angle is 90°, and another half of that, then it must be 45° and so the third angle is also 45°. There is an infinite number of unique triangle with these angles. They are called similar triangles.
No. All equilateral triangles are isosceles, but not all isosceles triangles are equilateral.
yes. all triangles.
Yes. But not all isosceles triangles are equilateral.
All Triangles have 3 Sides. The only thing that is unique about an equilateral triangle is all 3 sides are the same length.
What is the names of all the triangles?
No. Only right triangles do, and not all triangles can be right triangles. Equilateral triangles, for example, are always 60°-60°-60°. Isosceles and scalene triangles can be right triangles; all isosceles triangles have the additional useful property of being able to be split into two right triangles.
The set of all triangles, probably.
