Question

(Mathematics Project) an exterior angle of an triangle is equal to the sum of its interior opposite angles By geometrically verify the statement ​

Answer 1

Answer:

x+y=z

Step-by-step explanation:

Let the exterior angle be z and the opposite interior angles be y and x

also, let a be the angle which is linear pair of z

now,

a= 180-z

also,

x+y+a=180 (angle sum property)

or, x+y+180-z= 180

or, z= x+y

Hence, proved
