A simple closed curve made up of only _____________ is called a polygon .
A polygon with minimum number of sides is
Polygons that have no portions of their diagonals in their exteriors are called
Convex polygons have each interior angle less than 180, so its vertices point outside. So there are no exterior diagonals in convex polygons.
Polygons that have any portions of their diagonals in their exteriors are called
All the sides of a regular polygon are _________________.
All the angles of a regular polygon are of ________________.
Sum of all interior angles of a polygon with (n) sides is given by
Maximum number of right angles in a right angled triangle are
Sum of all interior angles of a parallelogram is
The angle sum of all interior angles of a convex polygon of sides 7 is
Each exterior angle of a regular hexagon is of measure
The number of sides in a regular polygon is15, then measure of each exterior angle is
The measure of each interior angle of a regular polygon is 140^{o}, then number of sides that regular polygon has ___
The corresponding exterior angle must be 180140 = 40 degrees
The sum of ALL the exterior angles is ALWAYS 360.
exterior angles = 360/40 = 9
Therefore, number of sides = 9
Which of the following polygons is convex polygon ?
Which of the following is concave polygon?
To construct a parallelogram we need to know:
Answer: (c) Two adjacent sides and one angle
Hint: Parallelogram has its parallel sides equal. Also, if one angle is known to us, then we can determine the other angle since the two angles are supplementary.
A quadrilateral which has 2 pairs of equal adjacent sides but unequal opposite sides is called ________________.
The value of x in the following figure is:
Each interior angle of a regular pentagon is 108^{o}
The value of x in the following figure is
A parallelogram each of whose angles measures 90^{o }is _____________.
A parallelogram whose all sides are equal is called
Rhombus is a type of parallelogram whose all sides are equal
The diagonals of a rhombus bisect each other at _________ angles.
The diagonals of a rhombus are perpendicular bisectors of each other.
Diagonals of a rectangle:
Take a rectangle with 2 diagonals and take 2 triangles who include different diagonals . the triangles can be proved congruent and hence the diagonals can be proved equal.
The diagonals of a square bisect each other at _________ angle.
The least number that is divisible by all the numbers from 1 to 10 (both inclusive) is
Minimum possible interior angle in a regular polygon is ___________.
Maximum possible exterior angle in a regular polygon is ___________.
How many sides does a heptagon have ?
Name the closed figure with 4 sides ?
How many diagonals does a regular Hexagon has?
What is the number of sides in Hexagon ?
What is the sum of the measures of angles of a convex quadrilaterals?
If the three angles of a quadrilateral are 120^{o}, 130^{o}, 10^{o} then what is the fourth angle ?
The opposite angles of a parallelogram are __________________.
The perimeter of parallelogram PQRS is:
Perimeter of a parallelogram =sum of all sides. Since opposite sides of a parallelogram are equal, perimeter of parallelogram is 12+12+7+7=38cm
The diagonals of a square are ________________ each other.
If in a parallelogram its diagonals bisect each other and are equal then it is a,
How many measurements can determine a quadrilateral uniquely?
Diagonals of a parallelogram _______________ each other.
