Without using the Pythagoras theorem, show that the points (4, 4), (3, 5) and(–1,–1) are the vertices of a right angled triangle.
which grade Q's are u asking ?
i hve give the exam for 12th this year.
u know pythagoras theorem and distance formula ?
Use the distance formula.
No I an very weak at co-ordinate geometry :'(
Distance between points (x1,y1) and (x2,y2) is \(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\) does this help ??
@goformit100 then there is one concept - Distance formula. If (x1,y1) and (x2,y2) are two given points on any co-ordinate plane, the distance b/w 2 points is given by - \[\sqrt{(x1-x2)^2 + (y1-y2)^2}\]
@hartnn How to use it here ?
take 2 points at a time (4, 4), (3, 5) x1 = 4 y1 =4 x2 = 3 y2=5 d1=... ?
ok , I got it Thank You Sir
