It is used to mark or scribe lines at 90 degrees (right angle) to a straight edge.
Also used to check two adjacent edges are at 90 degrees (right angle)
The square root of -1 is "i". However engineers use "j", but it's essentially the same thing.
Triangles are rigid, quadrilaterals are not - a square can be "squashed" into rhombus.
The canonical example is the square root of -1. Mathematicians use the symbol i to represent it, electrical engineers use j because i is already busy.
it measures the right angled way of a square or any other shapes (90 degrees )
Engineers use blueprints so that they can see what the height and width of a object is going to be and how to make it.

Yes.
Electrical engineers use it in calculating power factor and electrical load distribution when dealing with 3 phase power connections.
Robotics engineers use scientific notation to compute very large or very small numbers.
Building engineers use math to help them figure out how big or how small to make the house or whatever they are building.
Engineers commonly use the IEEE (Institute of Electrical and Electronics Engineers) citation style for their research papers and publications. This style provides guidelines for formatting citations and references in engineering-related fields.
