Drawing materials PaperPaper is made of cellulose that is obtained from treesThe paper size that we use is A4 . Sizes: 297x210 mm
Pencils and rubbersA pencil has a lead covered with wood. The lead ismade with graphite and clay (the more clay itcontains the harder the lead will be). We use letterH for hard pencils and letter B for soft ones. Very Hard Medi Soft Very hard um soft 6H 5H 4H 3H 2H H HB B 2B 3B 4B 5B 6B
THE RULERIt is a precision tool that allows you to measure and transfer distances.TRIANGULAR SET SQUAREA set square is a tool for drawing parallel and perpendicular lines and for getting angles.There are 2 types of triangular set squaresA 45 degree A 60 degree
Parallels and perpendicularsParallels in vertical: Parallels in horizontal:
How to use drawing toolsDrawing angles: we can get 15º, 30º, 45º, 60º, 75º,90º, 120º, 135º…angles by combining the 30º, 45º, 60º and the 90º angles from the set squares
You can get 45º, 75º, 90º, 120º angles combining the set squares
ACTIVITIES:1st: Draw the set squares in your notebook as you can see them inboth positions2nd: Draw a chessboard using the set square. The separation betweensquares is 2 cm!3rd: Drawing angles exercise: you have to obtain, 45º, 75º, 90º,120º angles combining the set squares
