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.

The group, Flexible School Admissions for Summer Born Children, says the school starting age for summer babies has in effect become four, not five. Under current law, children in England must be in education from the term after their fifth birthday. But the law also allows for pupils to start school earlier. As a result, the vast majority of children begin their education by taking up a Reception class place at the age of four.
