$\huge{\underline{\bold{Quadrilaterals :}}}$

A plane figure bounded by four line segments.

A quadrilateral is a two dimensional figure with four sides. It is also termed as polygon.

It has four sides, two diagonals and four vertices.

It is written as quad. ABCD or □ABCD.

In a quad. ABCD, we have ;

1️⃣ $\underline{\large{\bold{Veritices :}}}$ The points A, B, C, D are called the vertices of quad. ABCD.

2️⃣ $\underline{\large{\bold{Sides :}}}$ The line segments AB, BC, CD and Da are called the sides of quad. ABCD.

3️⃣ $\underline{\large{\bold{Diagonals :}}}$ The line segments AC and BD are called the diagonals of quad. ABCD.

4️⃣ $\underline{\large{\bold{Adjacent \: sides:}}}$ Two sides of a quadrilateral having a common end point, are called its consecutive are adjacent sides.

(AB, BC), (BC, CD), (CD, DA) and (DA, AB) are four pairs of adjacent sides of quad. ABCD.

5️⃣ $\underline{\large{\bold{Opposite \: sides:}}}$ Two sides of a quadrilateral having no common end point are called its opposite sides.

(AB, CD) and ( AD, BC) are two pairs of opposite sides of quad. ABCD.

Answer 2

Q: What is Quadrilateral ?

A closed figure bounded by four line segments is called a quadrilateral. A quadrilateral PQRS has the following elements. ( see the figure)

✯Four vertices P, Q, R and S.

✯Four sides PQ, QR, RS and SP.

✯Four angles ∠P, ∠Q, ∠R and ∠S.

✯Two diagonals PR and QS.

✯Four pairs of adjacent sides (PQ, QR), (QR, RS), (RS, SP) and (QR, PS).

✯Two pairs of opposite sides (PQ, QR) and (QR, PS).

✯Four pairs of adjacent angles (∠P, ∠Q), (∠Q, ∠R), (∠R, ∠S) and (∠S, ∠P).

✯Two pairs of opposite sides (∠P, ∠R) and (∠Q, ∠S).

✯The sum of the four angles of a quadrilateral is 360°
