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.

2.4 Age at school entry. As noted above, the entrance policy in Scotland allows that children are eligible to start to school when they are aged between 4.5 and 5.5 years old. However, this policy also allows the flexibility for children at the younger end of the spectrum to have their entry deferred for a year meaning that a small proportion of children will be slightly older than 5.5 at the time of entry.
