Question

what are the total degree of all angles of a triangle?

(a)360°
(b)90°
(c)180°
(d)270°​

Answer 1

Answer:

c)180°

Step-by-step explanation:

all interior angles of triangle sum 180° and exterior angles sum 360°

Answer 2

Step-by-step explanation:

180°

let the value of angle A,B,C =angle=1,2,3

$\small \color{magenta}{ \boxed{ \color{gold}{ \boxed{ \color{green}{to \: prove}}}}}$

1+2+3=180

$\small \color{red}{ \boxed{ \color{green}{ \boxed{ \color{magenta}{construction}}}}}$

draw a line parallel to BC name it as L

$\small \color{green}{ \boxed{ \color{blue}{ \boxed{ \color{gold}{solving \: the \: question}}}}}$

angle 2= angle 4 (alternate angles)

angle 5=angle 3 (alternate angles)

ATQ

angle1+angle 2+angle 3=angle 1 +angle 2 +angle 3 (using linear pair)

angle1+angle 2+angle 3=180°
