Answer 2

$\huge\bold{QUESTION}$

State the angle sum property of a triangle.?

$e\bold{solution}$

⁣            Since PQ is a straight line, it can be concluded that:

⁣       ∠PAB + ∠BAC + ∠QAC = 180° (1)

Since PQ||BC and AB, AC are transversals,

Therefore, ∠QAC = ∠ACB (a pair of alternate angle)

⁣           Also, ∠PAB = ∠CBA (a pair of alternate angle)

⁣           Substituting the value of ∠QAC and∠PAB in equation (1),

$\bold{∠ACB + ∠BAC + ∠CBA= 180°}$

Thus, the sum of the interior angles of a triangle is 180°.
