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.

School is compulsory from the age of six. Children can enter non-compulsory Transition at the start of the school year if they turn five by 30 June that year. To enter Year 1 (compulsory) children must turn six before 30 June in the year they are enrolled.
