Homework Help Overview

The discussion revolves around a problem related to calculating areas in a geometric context, specifically involving triangles and parallelograms, as well as the concept of a "slicing corner." Participants are exploring the relationships between different geometric shapes and their areas, particularly in three dimensions.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning, Problem interpretation

Approaches and Questions Raised

  • Participants discuss various formulas for calculating the area of triangles, including the cross product method and the base-height formula. There is an exploration of how to apply these formulas to find the area of a specific triangle in the context of the problem.

Discussion Status

The discussion is active, with participants providing hints and asking clarifying questions. Some have successfully calculated areas using the cross product, while others are still seeking guidance on how to approach the problem and clarify their understanding of the geometric relationships involved.

Contextual Notes

There are indications of confusion regarding the definitions and relationships of the geometric components involved, as well as the need for clarity on the original problem's requirements. Participants are also navigating the constraints of homework rules that limit direct assistance.

oh you mean the actual values?
A= ab/2
B= ac/2
C = bc/2

D = 1/2(ab+bc+ac)?

Now I'm completely lost …

what parts of the square are A B C D a b and c ? :confused:

what square?
Im talking about the sliced part...
i'm confused now lol..
 
  • #33
your square :confused:

cube - square
sliced corner - triangle
sliced plane - line?

yes …

next, the 3D equation was about a sum of areas squared …

so what would be 2D equivalent of that be?

how do i do this?
