What is a sketch?

• A detailed and complex drawing

• A quick, simple drawing

• A drawing made with instruments

• A painting

Which of the following is true about freehand sketching?

• It requires the use of rulers and squares

• It is done manually without the aid of instruments

• It is always done on isometric graph paper

• It is a type of perspective sketching

What is the main characteristic of isometric sketching?

• It uses a 90-degree angle between axes

• It uses a 60-degree angle between axes

• It uses equal angles of 120 degrees between axes

• It uses a single vanishing point

Which type of paper is used for isometric sketches?

• Square graph paper

• Isometric graph paper

• Lined paper

• Plain paper

What is the purpose of construction lines in drawing?

• To add color to the drawing

• To serve as guides while sketching or drawing

• To create shadows in the drawing

• To outline the final drawing

How does perspective sketching differ from isometric sketching?

• Perspective sketching uses equal angles between axes

• Perspective sketching is more realistic and similar to human vision

• Perspective sketching is done without any guidelines

• Perspective sketching is always done on isometric graph paper

Identify the shape that is described as an elongated circle.

• Circle

• Ellipse

• Triangle

• Square

Explain why isometric axes are set at 120 degrees relative to one another.

• To create a realistic 3D view

• To ensure equal spacing between lines

• To maintain equal angles for accurate representation

• To simplify the drawing process

What is the optical illusion created by perspective in drawings?

• Lines appear parallel

• Lines appear to diverge

• Parallel lines converge and vertical lines become shorter

• Lines appear to be the same length

How can isometric graph paper assist in creating isometric sketches?

• By providing a grid of squares

• By providing a 60° grid of small triangles

• By providing a grid of circles

• By providing a plain surface
