it is use to measure angle in their house or etc.
Carpenters, Builders, Engineers, Surveyors, Architects, Mathematicians, Astronomers and in general many other people from all walks of life use angles to carry out their jobs.
Using angles makes it easier for electrical engineers, software engineers, mechanical engineers, surveyors, architects, rally drivers, soldiers, sailors, etc to do their jobs.
Well, honey, angles are like the seasoning of the math world - they're sprinkled everywhere! Jobs like architects, engineers, and construction workers use angles daily to design and build structures. Even fashion designers use angles to create patterns and clothing that actually fit. So, if you're good with angles, you've got options galore, darling!
Engineers and architects use angles for designs, roads, buildings and sporting facilities. Without angles you wouldn't have the correct height of a ceiling or the correct angel of the roads.
They use it to measure angles and lengths
A protractor is the common tool used in mathematics for measuring and drawing angles.

Possibly a protractor...
Architects use math in everything from angles to finding the area of a building.
Carpenters use geometry for angles and diagonal lengths, area and surface area for walls and sheathing, and the engineering computation of loads per square inch.
