NCERT MATHS Class 9 Chapter 8 Quadrilaterals Exercise 8.1, Q-1 and 2

NCERT MATHS Class 9 Chapter 8 Quadrilaterals Exercise 8.1, Q-1 and 2 Here is a simple, exam-ready description for NCERT Class 9 Maths – Chapter 8 (Quadrilaterals), Exercise 8.1, Q-1 & Q-2, along with hashtags 👇 🔹 Question 1 Description If the diagonals of a parallelogram are equal, then show that it is a rectangle. In this question, we prove that when the diagonals of a parallelogram are equal in length, the angles between its sides become right angles. Since a rectangle is a special type of parallelogram with equal diagonals and all angles equal to 90°, the given parallelogram satisfies the properties of a rectangle. Hence, a parallelogram with equal diagonals is a rectangle. 🔹 Question 2 Description Show that the diagonals of a square are equal and bisect each other at right angles. A square has all sides equal and all angles equal to 90°. In this question, we show that the diagonals of a square are equal in length. They also bisect each other at their midpoint and intersect at right angles (90°). These properties confirm that the diagonals of a square are equal, perpendicular, and bisect each other. 📌 Hashtags #NCERTMaths #Class9Maths #Quadrilaterals #Exercise8_1 #Parallelogram #Rectangle #Square #Diagonals #CBSEMaths #MathsConcepts If you want, I can also provide step-by-step proofs or short exam answers 😊
