Discussion Overview

The discussion revolves around a homework problem involving the calculation of the perimeter of a quadrilateral formed by the midpoints of the sides of a given quadrilateral with specified vertices. The focus is on understanding the steps needed to solve the problem, including finding midpoints and determining the perimeter.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant expresses uncertainty about how to approach the problem due to missing class instruction.
  • Another participant suggests starting by finding the midpoints of the sides of the quadrilateral.
  • A different participant indicates they have figured out the midpoints and suggests connecting them to determine the perimeter of the new shape.
  • One participant claims to have calculated the perimeter as 20.2 and expresses regret about the thread's usefulness.

Areas of Agreement / Disagreement

The discussion includes varying levels of understanding and confidence among participants, with no consensus on the method or final answer being established.

Contextual Notes

Some assumptions about the method for calculating the perimeter and the accuracy of the claimed answer remain unverified, and the discussion does not resolve the steps involved in finding the midpoints or the perimeter.

I don't know how to tackle this question as I was absent from class the day it was taught but I need to know:

A quadrilateral has vertices P(0,8) Q(-4,4) R(2,-2) and S(6,4). Find the perimeter of the figure whose vertices are the midpoints of the sides of the quadrilateral.

Firstly, this belongs in the homework section. Do you know how to start the question? Can you find the midpoints of the sides of the quadrilateral to start with?
 
Yes, I think I got it now. I had them figured out all along I just found the question wordy and didn't know where to go from next. I think I have it now, you get the midpoints, connect the dots with lines (in my head) and figure the perimeter of the new object.
 
Yeah I got the answer, it was 20.2. Sorry for the useless thread.
