No product results in -1, hence δlmn is NOT a right triangle showing that  lydia's assertion is incorrect

<h3>Perpendicular lines</h3>

In order to determine whether triangle lmn  is right-angled, we need to determine the slope of lm, ln, and mn first as shown:

For the slope of lm:

m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1

For the slope of ln:

m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\

For the slope of mn:

m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\

  • If any of the two lines is perpendicular, hence the triangle lmn is right-angled.

  • To check, we will take the product of the slopes and see if it is equivalent to -1.

Product of slope lm and ln

m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2

Since no product results in -1, hence δlmn is NOT a right triangle showing that  Lydia's assertion is incorrect

<h3>How to classify direct or Indirect Costs?</h3>

1. Frames and tires used in manufacturing bicycles; This cost would be classified as Direct materials.

2. Wages paid to production workers; This cost would be classified as Direct Labor as that is what it is used for.

3. Insurance on factory equipment and machinery; This cost will be classified as Manufacturing Overhead because it involves overheads necessary for manufacturing.

4. Depreciation on factory equipment; This cost will be classified as Manufacturing Overhead because it involves overheads necessary for manufacturing.

Complete question is;

Determine whether each of the following costs should be classified as direct materials, direct labor, or manufacturing overhead.

1. Frames and tires used in manufacturing bicycles.

2. Wages paid to production workers.

3. Insurance on factory equipment and machinery.
