What is NOT an example of a geometric constraint?
- A.
Parallel lines
- B.
Horizontal and vertical lines
- C.
Isometric shapes
- D.
Perpendicular lines
Correct Answer
C. Isometric shapesExplanation
Isometric shapes are not an example of a geometric constraint because they do not restrict or define the relationship between different elements or objects in a geometric system. Geometric constraints typically involve the positioning, orientation, or alignment of geometric elements, such as lines or shapes, in relation to each other. Isometric shapes, on the other hand, refer to a specific method of representing three-dimensional objects on a two-dimensional plane, using equal angles and equal distances to create the illusion of depth. Therefore, isometric shapes do not impose any specific constraints on the relationships between geometric elements.Rate this question:

Research, because a design brief gives criteria to research.
- D.
Communicate Results, because design briefs deal with clients.
Correct Answer
A. Define the Problem, because the problem is given to you by a client.Explanation
The correct answer is "Define the Problem, because the problem is given to you by a client." This step in the design process uses a design brief because it helps the designer understand the specific problem or challenge that needs to be addressed. The design brief is typically provided by the client and outlines their requirements, objectives, and constraints. By analyzing the design brief, the designer can gain a clear understanding of what needs to be achieved and can then proceed to develop solutions and ideas accordingly.Rate this question:

Correct Answer
D. A systematic problem-solving strategy, with criteria and constraints, used to develop many possible solutions to a problem or to satisfy human needs and wants and narrow down the possible solutions to one final choice.Explanation
The design process refers to a systematic problem-solving strategy that involves the development of multiple potential solutions to a problem or the satisfaction of human needs and wants. It includes the consideration of criteria and constraints, which help to narrow down the possible solutions to eventually select one final choice. This process ensures that engineers approach problem-solving in a structured and organized manner, taking into account various factors and considerations before making a final decision.Rate this question:
