Question

Verify experimentally that the sum of all interior
angles of a triangle is 180º. (Two figures of
different measurements are required.)​

Answer 1

MARK ME AS THE BRAINLIEST

Step-by-step explanation:

here in ABC

angle CAB = angle RCA (alternate interior angles)

angle CBA = angle SCB (alternate interior angles)

so, angle RCA + angle SCB + angle ACB = 180° (straight line)

which will imply

angle A + angle B + angle C = 180°

HENCE PROVED

More To Know :-

• A triangle is a polygon with three edges and three vertices.

• A triangle with vertices A, B and C is denoted as ∆ABC.

• Sum of all angles of a triangle is always 180°.

• The measure of an exterior angle is sum of it's two interior angles that are not adjacent to it.
