Hi friends!

The pentagon is a very interesting figure and many buildings have been built using this shape as a base.
Today I want to show you how a five-sided figure (a pentagon) is geometrically constructed. I will also show you how to project this geometric figure in perspective.

-----------------------------------------------

We start by drawing a circle and then dividing it into four by plotting the vertical and horizontal diameters.
Divide the horizontal radius of the circle in two, then draw a segment from "r/2" to "a" as shown below.

With a drawing compass measure the segment "a - r/2" and draw the arc "ab" intersecting the horizontal diameter.

Now, measure the distance "a - b" and intersect the circle as shown.

Repeat the measurement by crossing around the circle to get the five divisions.

This is the result, a pentagon, that is, a regular shape with five sides.

Now, to draw in perspective you can project this shape in the position you want, always inside the circle. To do this, you must first draw a square in a perspective view and then a circle inscribed in it.
You will get the pentagon drawn in perspective by drawing vertical lines from each corner of the shape until they intersect the circle drawn below the horizon line.

Esta es una vista más elevada, el proceso de dibujo es el mismo.

See in the previous post another example of how to project a pentagon in perspective.

I wish you a very nice day and good exercise!

And if you like to colour your drawings, I recommend the interesting and useful Color and Light classes of @fumansiu whose concepts you can apply both with traditional and digital techniques.

is his newest lesson.
Very interesting indeed!

Or maybe you want to make a beautiful watercolour with your drawing!
Well, our friend @arcoiris is back with his magnificent watercolour lessons.
