Question

prove that the points (7 10) (-2 5) and (3 -4) are the vertices of an isosceles right triangle

Answer 1

Answer:

It can be calculated by finding out lengths.

Step-by-step explanation:

$\sqrt{(10 - 5) ^{2} + (7 - ( - 2)) ^{2} } </p><p></p><p></p><p>\\ \sqrt{(7 - 3) ^{2} + (10 - ( - 4)) ^{2} } </p><p></p><p>\\ \sqrt{(-2 - 3) ^{2} + (5 - ( - 4)) ^{2} }</p><p>$

Similarly we can find out remaining legths & we can see if two lengths are equal .

Length 1 =√(25+81) = √106

Length 2 =√(16+196) = √212

Length 3=√(25+81) = √ 106

1. We an see that two lengths are equal so triangle is isosceles .
