**1. Is scoring high marks in math exams tough?**

No, Scoring high marks in maths exam can be achieved through a clear understanding of the syllabus, maintaining a daily study routine, thorough learning from the right study materials, focusing on high weightage chapters more, preparing a revision note for the last minute revision, staying calm and focused, solving more previous year question papers, managing time and by giving your best at the exam. We hope this will be helpful to have an idea on how to score good marks in maths.

**2. What are various types of quadrilaterals?**

**Rectangle-**A quadrilateral in which the opposite sides are equal and parallel to each other. All the interior angles of a triangle are 90 degrees**Square-**A quadrilateral where all the sides are equal and all the interior angles are 90 degree**Parallelogram-**Which has parallel opposite sides.**Rhombus-**It is a kind of parallelogram, where all the sides are equal.**Trapezium-**Only a pair of the four sides are parallel to each other.

**3. What are the important attributes of a quadrilateral?**

The following are some of the important attributes of quadrilaterals

**Vertices:**points where two sides or edges meet.**Sides:**The four-line segments of a quadrilateral are called its sides.**Angle:**It is the meeting point of two sides.**Adjacent sides:**The two sides which have a common endpoint.**Adjacent angles:**Angles that have one common arm onto the sides**Opposite sides:**The sides which don’t meet at any point.**Opposite angles:**Two angles, which are not adjacent angles.**Interior of a quadrilateral:**It is the enclosed part within the quadrilateral.**The exterior of a quadrilateral:**In this, points are not enclosed within the quadrilateral.

**4. What are the essential properties of Quadrilaterals**

A diagonal is a line that joins two non-consecutive vertices of a polygon.

The Interior of a closed curve has a fixed boundary, but the exterior has no limit.

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

The diagonals of a square are perpendicular bisectors of each other.

n – 2 provides the number of triangles in a polygon.

The sum of the interior angles of a polygon is given by the formula = (n-2)X180°

The exterior angle of a polygon can be calculated by dividing 360 with the number of sides of a polygon.
