1 answers

Sia ? 4 years, 4 months ago

Coordinate of Point R is ( 4 , 3 ).

Step-by-step explanation:

Given Coordinates of the Points are

P ( 1 , 0 ) , Q( 4 , 0 ) and S( 1 , 3 )

We need to find: Coordinate of the point R such that PQRS is a Square.

First we mark all the given points on the Graph.

Then see where the Point R lies satisfying that PQRS is a Square.

1st Graph Attached has all 3 given point marked.

Clearly from graph 1. Coordinate of Point are must be on line x= 4 and y = 3

So, Coordinate of point R is intersection of lines x = 4 and y = 3

that is (4 , 3).

Therefore, Coordinate of Point R is ( 4 , 3 ).

Dear Diary:

Today I am going to share with you my feelings about my visit to a school for the blind. The school conducted this trip as a part of social service and moral education class. I was really moved to see these special children with visual disabilities. I saw them studying with unique focus. Though technology has developed special audio and Braille books for them, but still their deprivation was tangible. The one thing I liked the most about them was their zest for life. They seemed to be least affected by their deprivation. Interacting with them I felt so humble! I also realized how fortunate I am to have this blessing of vision. I wish all those children and all the people in the world who are suffering from visual deprivation all the success, health, and contentment. God bless all of them!
