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.

One of the last areas in Europe to adopt a compulsory system was England and Wales, where the Elementary Education Act of 1870 paved the way by establishing school boards to set up schools in any places that did not have adequate provision. Attendance was made compulsory until age 10 in 1880. The Education Act of 1996 made it an obligation on parents to require children to have a full-time education from the age of five to the age of sixteen. However, attendance at school itself is not compulsory; Section 7 of the Act allows for education otherwise than at a school i.e. home education.
