Step-by-step explanation: Given 3 vertices of triangle that are P(0,1), Q(0,5)and R(3,4). We have to find out the area formed by 3 vertices of triangle. Here the triangle which is formed has base 4 units and height 3 units as shown in attachment. Area of triangle ABC is \frac{1}{2}\times base \times height21×base×height = \frac{1}{2}\times 4 \times 321×4×3 = 6 sq units

Consider the triangles AEB and CDB
{tex}\angle{/tex}EBA = {tex}\angle{/tex}DBC ... (Common angle) ... (i)
Further, we have:
{tex}\angle{/tex}BEA = 180 - y
{tex}\angle{/tex}BDC = 180 - x
Since x = y, we have:
180 - x = 180 - y
{tex}\angle{/tex}BEA = {tex}\angle{/tex}BDC ... (ii)
AB = CB ... (Given) ... (iii)
From (i), (ii) and (iii), we have:

Sia ? 4 years, 3 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 ).
