There are many ways to solve a maths question.
Normally it involves taking many steps with related sequence.
However, there are also simple ways to handle a maths problem.
One such solving method is simply through visual steps.
This has no working at all.
What do I mean?
Let's look at an example.
Determine the angle B from the diagram below. Angle A is 40 degree.
Angle B is same as angle A = 40 degree.
There is no working at all. Just the visual determination.
Concept of this trigonometrical question in geometry:
When 2 straight lines cross and meet at an angle to each other, the angle opposite to any one is the same.
As such, angle C is also equal to angle D.
This is visual maths.
