Answer 1

A= 1/6*180 = 30 degrees
B= 2/6*180=60 degrees
C= 3/6 * 180 = 90 degrees
So ABC is a right triangle
BC=1/2AB
BC/AB=1/2

Answer 2

Step-by-step explanation:

$angle \: a:b:c = 1 : 2 : 3$

$1x + 2x +3 x = 180 \\ angle \: sum \: property \: of \: triangle$

$6x = 180$

$x = \frac{180}{6} = 30$

ஃ angle A = 1x = 1(30) = 30

angle B = 2x = 2(30) = 60

angle C = 3x = 3(30) = 90

it is a right angle..
