Sum of linear pair angles = 180°
∠ABC + 130° = 180
∠ABC = 180 - 130
∠ABC = 50°
Sum of linear paired angles = 180°
∠PRQ + 140° = 180°
∠PRQ = 180° - 140°
∠PRQ = 40°
Given in question, ΔABC ≅ ΔPQR . So, ∠ABC = ∠PQR and ∠ACB = ∠PRQ
∠ABC = 50° = ∠PQR
∠PRQ = 40° = ∠ACB
∴ In ΔTQC, ∠TQC = ∠PQR { from figure }
∠TQC = 50°
∠TCQ = ∠ACB { from figure }
∠TCQ = 40°
Sum of all angles in a triangle = 180°
∠TCQ + ∠TQC + QTC = 180°
50° + 40° + ∠QTC = 180°
∠QTC = 180° - 90°
∠QTC = 90°
We know that opposite angles are equal,so ∠QTC = ∠ATP
∠ATP = ∠QTC = 90°
Therefore,, measure of ∠ATP is 90°
