Are some isosceles triangles equilateral triangles?
All isosceles triangles are not equilateral triangles
Does pythagoras' theorem work for all triangles?
no only right triangles
How A pentagon can be divided into how many triangles by drawing all of the diagonals from 1 vertex?
Three triangles
Is a triangle a symmetric shape yes or no?
Some triangles are symmetric, while others are not. All equilateral and isosceles triangles are symmetric.all triangles are symmetric.
If all of the diagonals are drawn from a vertex of an octagon how many triangles are formed?
5 triangles are formed.
Why is there a orthocenter?
There just is :)In all seriousness, all triangles (by definition) have an orthocenter and other points of concurrency. The definitions of an orthocenter is the place where the altitudes of all three sides intersect.
Triangles and their names?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are: scalene, right angle, obtuse, isosceles and equilateral triangles
Where can you search names by definitions?
in the incex
Some equilateral triangles are not isosceles?
All isosceles triangles are not equilateral triangles
Are all equilateral triangles acute triangles?
Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.
Are all triangles semmetrical?
No. But all isosceles triangles and equilateral triangles are.
Are some isosceles triangles equilateral triangles?
All isosceles triangles are not equilateral triangles
Are all triangles polgons?
yes. all triangles.
What are the names of the three triangles?
Equilateral, Isosceles and Scalene.
What are two triangles names?
Squares and polygons. DumbA**
Are all equilateral triangles also isoscelles triangles?
Yes. But not all isosceles triangles are equilateral.
Do all triangles have right angles?
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.
