COLOURS

1.- What is the difference between value and a hue's pure value?

Value: describes the lightness or darkness of a colour.

Hue: is the name for each pure colour found in the colour spectrum.

2.- Write a definition of primary and secondary colours. List each and describe how we obtain them.

Primary colours: There are the colours that do not come from a mix of colours but all others colours come from them.

Secondary colours: We obtain these colours by mixing the same of two primary colours.

3.- What are the warm colours? Why are they called like this?

Convey a sensation of warmth.

4.- Give one example of how we can contrast colours in a composition.

The sensation of size: A colour can make a form seem bigger or smaller.

The sensation of distance: A colour can appear close or further away.

The sensation of weight: A colour can make a form seem heavier or lighter in weight.

          GEOMETRIC OPERATIONS

1.- Write a definition of a segment bisector.

A segmental bisector is the perpendicular line that divides a segment into two equal part.

2.- What is an angle.

An angle is the part of plane defined by two straight lines that cross at the same point, called vertex

3.- Explain the steps we must follow to divide a segment into five equal parts.

1, draw a line r from point A of segment AB

2,mark as many a point on this line as the number of segments you wish to divide segment AB into5,

3, Join the last point to point B. Draw lines that are parallel to B5 from points 4,3,2 and 1. We will now have our segment AB divided into the equal number of parts we wanted.
