the idea that the people have the right to abolish an abusive and unresponsive government was first formally expressed by americ
lawyer [7]

Americans formally stated in the Declaration of Independence that the people have the right to abolish an abusive and unresponsive government.

The Declaration's fundamental principle was that all "men are born and remain free and equal in rights" (Article 1), which were defined as the rights to liberty, private property, person inviolability, and resistance to oppression (Article 2).

The Declaration of Independence was written so that the thirteen colonies could declare their independence from Britain.The Declaration of Independence's introductory sentence states the Declaration's main purpose, which is to explain the colonists' right to revolution.  To put it another way, "to proclaim the reasons for their separation."

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's asserti
nadya68 [22]

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
