Of course, the main property of isosceles triangles is their two congruent sides. All isosceles triangles also have base angles that are congruent. Again, this property holds true for all isosceles triangles, no matter which direction their apex points.
In France, children start school at three years old (although it is not compulsory until six years old). A comparison between my daughter (educated in France) and her cousin (in the UK) at exactly 4 yrs 9 1/2 months old showed that a British education gives kids the tools they need to read and write much more quickly.

Optional Kindergarten (nursery school) education is provided for all children between two and six years of age, after which school attendance is compulsory.
