Question

show that the point 20 - 20 and 02 are the vertices of a triangle​

Answer 1

let (2,0) be A

let (-2,0) be B

let (0,2) be C

distance AB = 4

distance BC = 2√2

distance AC = 2√2

a triangle is an isosceles triangle if two sides are equal

here, 2 sides are equal

therefore it is an isosceles triangle

Answer 2

Answer:

let (2,0) be A

let (-2,0) be B

let (0,2) be C

distance AB = 4

distance BC = 2√2

distance AC = 2√2

a triangle is an isosceles triangle if two sides are equal

here, 2 sides are equal

therefore it is an isosceles triangle
