Look at these drawings. How are they different?

Technical drawing is a “universal language” used in the creation of any man-made object.  It gives us the necessary information to fabricate any object. 

Can you think of any tools we might use? ď&#x201A;&#x17E; A ruler: is used to draw straight lines and to measure. ď&#x201A;&#x17E;

Set squares are used to draw lines, parallels and perpendiculars. ď&#x201A;&#x17E; They are both right triangles (triangles with one right angle). ď&#x201A;&#x17E; One is an isoceles triangle and the other is a scalene triangle. ď&#x201A;&#x17E;

ď&#x201A;&#x17E;

The compass is used to draw archs and circles.

Paper is the surface for technical drawings. ď&#x201A;&#x17E; The sizes of the paper are normalized. The largest is A0 and the smallest is A8. ď&#x201A;&#x17E;

Pencils are the medium for technical drawing. ď&#x201A;&#x17E; They range from 6H (the hardest) to 8B (the softest). ď&#x201A;&#x17E;

A line

A ray is a line the ends in a point but continues with an infinite line

A segment is a line that ends in two points

ď&#x201A;&#x17E;

An angle is the space between two intersecting lines.

There are four types of angles: › Acute: Angles that measure less

than 90º › Right: Angles that measure 90º › Obtuse: Angles that measure

more than 90º › Straight: Angles that measure

180º

ď&#x201A;&#x17E;

The drawing of perpendicular, parallels, and angles are fundamental when drawing more complex geometric constructions.

ď&#x201A;&#x17E;

Take your compass, ruler, set squares and pencil.

The bisector is the perpendicular line that divides a segment in two equal parts.  Follow the steps:  http:// www.mathopenref.com/constbisectline.htm 

Using the skills you have learned, try to replicate the shape below:

We will design the house of your wildest dreams! ď&#x201A;&#x17E; Take a look at some famous architecture ď&#x201A;&#x17E;

• Requirements for the dream house design: • Draw the floor plan and the front elevation. • Include at least 1 circle, 1 square or rectangle, 1 triangle and 1 hexagon. • Extra points: draw the isometric perspective
