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.

Children must enroll at school by six years. From 2014, all children will start school on the first day of term one in that year so that every child will have four terms of Reception when they go to school. If your child: turns five before 1 May they will start school on the first day of term one in that year.
