Test: Practical Geometry- 2 - Question 1

A simple closed curve made up of only _____________ is called a polygon .

Detailed Solution for Test: Practical Geometry- 2 - Question 1
A simple closed curve made of three or more line-segments is called a polygon. A polygon has at least three line-segments.
The line-segments of a polygon are named by the sides in it. Poly means many and gon means sides. Thus a polygon has many sides.

Test: Practical Geometry- 2 - Question 3

Polygons that have no portions of their diagonals in their exteriors are called  

Detailed Solution for Test: Practical Geometry- 2 - Question 3

Convex polygons have each interior angle less than 180, so its vertices point outside. So there are no exterior diagonals in convex polygons.

Test: Practical Geometry- 2 - Question 4

Polygons that have any portions of their diagonals in their exteriors are called  

Test: Practical Geometry- 2 - Question 5

All the sides of a regular polygon are _________________.

Test: Practical Geometry- 2 - Question 6

All the angles of a regular polygon are of ________________.

Test: Practical Geometry- 2 - Question 7

Sum of all interior angles of a polygon with (n) sides is given by

Detailed Solution for Test: Practical Geometry- 2 - Question 7
Correct answer is option a because if we take the polygon triangle. the no.of side =3 so,the sum of its interior angle =180degree by this formula(n-2)×180degree 3-2×180degree =180degree so proved.
Test: Practical Geometry- 2 - Question 8

Maximum number of right angles in a right angled triangle are

Detailed Solution for Test: Practical Geometry- 2 - Question 8
Because the sum of a triangle is 180 degree and of right triangle is 90 degree and if there is two right triangle then their sum is 180 degree this is not possible to have two right angle in a right angle triangle.
Test: Practical Geometry- 2 - Question 9

Sum of all interior angles of a parallelogram  is

Test: Practical Geometry- 2 - Question 10

The angle sum of all interior angles of a convex polygon of sides 7 is

Test: Practical Geometry- 2 - Question 11

Each exterior angle of a regular hexagon is of measure  

Test: Practical Geometry- 2 - Question 12

The number of sides in a regular polygon is15, then measure of each exterior angle is

Detailed Solution for Test: Practical Geometry- 2 - Question 12
The formula of each exterior angle is 360/no.of sides so 15=360/n, then n = 360/15=24degree.
Test: Practical Geometry- 2 - Question 13

The measure of each interior angle of a regular polygon is 140o, then number of sides that regular polygon has ___

Detailed Solution for Test: Practical Geometry- 2 - Question 13

The corresponding exterior angle must be 180-140 = 40 degrees

The sum of ALL the exterior angles is ALWAYS 360.

exterior angles = 360/40 = 9

Therefore, number of sides = 9

Test: Practical Geometry- 2 - Question 14

Which of the following polygons is convex polygon ?

Test: Practical Geometry- 2 - Question 15

Which of the following is concave polygon?

Test: Practical Geometry- 2 - Question 16

To construct a parallelogram we need to know:

Detailed Solution for Test: Practical Geometry- 2 - Question 16

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.

Test: Practical Geometry- 2 - Question 17

A quadrilateral which has 2 pairs of equal adjacent sides but unequal opposite sides is called ________________.

Test: Practical Geometry- 2 - Question 18

The value of x in the following figure is:

Detailed Solution for Test: Practical Geometry- 2 - Question 18

Each interior angle of a regular pentagon is 108o

Test: Practical Geometry- 2 - Question 19

The value of x in the following figure is

Test: Practical Geometry- 2 - Question 20

A parallelogram each of whose angles measures 90o is _____________.

Test: Practical Geometry- 2 - Question 21

A parallelogram whose all sides are equal is called

Detailed Solution for Test: Practical Geometry- 2 - Question 21

Rhombus is a type of parallelogram whose all sides are equal

Test: Practical Geometry- 2 - Question 22

The diagonals of a rhombus bisect each other at  _________  angles.

Detailed Solution for Test: Practical Geometry- 2 - Question 22

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

Test: Practical Geometry- 2 - Question 23

Diagonals of a rectangle:

Detailed Solution for Test: Practical Geometry- 2 - Question 23

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.

Test: Practical Geometry- 2 - Question 24

The diagonals of a square bisect each other at  _________  angle.

Test: Practical Geometry- 2 - Question 25

The least number that is divisible by all the numbers from 1 to 10 (both inclusive) is      

Test: Practical Geometry- 2 - Question 26

Minimum possible interior angle in a regular polygon is ___________.

Test: Practical Geometry- 2 - Question 27

Maximum possible exterior angle in a regular polygon is ___________.

Test: Practical Geometry- 2 - Question 28
