The sum of angle of a triangle is equal to​

Answer 1

Answer:

The sum of angle of a triangle is equal to 180 degree

Step-by-step explanation:

In geometry, the interior angles of a triangle are the angles that are formed inside a triangle. Interior angles have the following properties: The sum of interior angles is 180 degrees (Triangle Angle Sum Theorem

Angles in a triangle sum to 180°

$\huge \fbox{\underline \orange{Proof-}}$

A triangle's angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the third angle to make a 180 angle.
