Question

Find the perimeter of a triangle formed by the points (0,0),(1,0),(0,1)

Answer 1

assume the vertices of triangle as
A(0,0)
B(1,0)
C(0,1)
All three points together forming a right angle triangle.
and latitude of this triangle l = 1unit
similarly base b = 1unit
so h Will be
h =
$\sqrt{ {1}^{2} + {1}^{2} } = \sqrt{2}$
here l,b,h are the length of the sides of the triangle.
now perimeter p = l + b + h
p =
$1 + 1 + \sqrt{2 } = 2 + \sqrt{2}$
answer p = 2+√2
p = 2+ 1.414
p = 3.414 unit
