In a rectangle PQRS, if m ∠QPR = 26°, then m ∠SQR = __________.

Correct option is A

​Given:
Rectangle PQRS, ∠QPR=26^∘

Formula Used:
In a rectangle, diagonals are equal and bisect each other

∠QPR+∠SQR=90^∘

Solution: 

​$$\angle QPR = \angle PQS \quad(\text{ diagonals are equal})$$ 

Thus, 

​$$∠QPR+∠SQR=90^∘$$​​

$$\angle SQR = 90^\circ - \angle QPR \\ \ \\ \angle SQR = 90^\circ - 26^\circ = 64^\circ$$​​
