Engineers use angle measurements to construct buildings, bridges, houses, monuments, etc.
Carpenters use angle measuring devices such as protractors, to make furniture like chairs, tables, beds, etc.
The angle can be seen in the wall clocks of our homes, made by hands of clocks. For example, if the small hand is in 3 and the big hand is in 12, then we get a right angle.
