Question

prove thaat the sum of all angles of triangles are 180°​

Answer 1

Consider a ∆ABC, as shown in the figure below. To prove the above property of triangles, draw a line ←→PQ P Q ↔ parallel to the side BC of the given triangle. Thus, the sum of the interior angles of a triangle is 180°.

Answer 2

Answer:

60+60+60=180

Step-by-step explanation:

Assume a triangle,

the corners make an angle which is 60 degree each

The sum of all the angle =180
