To iron a polo shirt, lay it flat and iron the front. If the sleeves are long, lay them flat on the ironing board on each side of the torso of the shirt and iron them. Then, flip the shirt over and iron the back.
A man named Henry Seeley was the inventor of the electric iron. Seeley invented the iron in 1882. That first iron, patented as an 'electric flatiron,' weighed 15 pounds. Seeley was from New York.
Iron wasn't invented. It is an ore and comes from iron mines. Steel is made from iron using a process of heating the ore and then removing the impurities from the ore through blowing air through it. The man who came up with this process was named Bessemer and his method is still used today.

Some, but not all. Triangles with 2 congruent sides are called isoceles triangles. Triangles with 3 congruent sides are called equilateral triangles.

if you're talking about 2 triangles that overlap, then yes and they are called overlapping triangles. XD
Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.
