Solve Geometry Exam

Introduction to solve geometry exam:

Geometry is a branch of mathematics that can be deals with the size, shape, position of shapes, and the properties of space. The geometry is also deals with the applications such as surveying, measurements, areas, and volumes. In Theoretical geometry or pure geometry, we give proofs for theorems on the properties of geometrical figures by applying axioms and reasoning. In practical geometry, we do not construct exactly the geometrical figures but draw rough sketches of the figures to give support to our logical reasoning. I like to share this Quadrilateral Formula with you all through my article.


Example problems to solve geometry exam:


Example problems to solve geometry exam are as follows:

1) The side length of cube is 10 cm. Find the volume of the cube.

Solution:

Formula for volume of the cube = a^3.
a= side length of the cube.

a=10 cm.

= (10)^3.

Volume of the cube =1000 cm^3.
This is the solution for the given geometry problem.


2)A triangle has a perimeter of 56. If 2 of its sides are equal and the third side is 8 more than the equal sides, what is the length of the third side?

Solution:

Let y = length of the equal side


Perimeter = sum of three sides.
Plug in the values from the question.
56 = y + y + y + 8

Combine like terms
56 = 3y + 8

3y = 56 – 8 (by equating the given equation)
3y = 48
y =16

Note: the third side is 5 more than the equal sides.

So, the length of third side = 16 + 8 =24

Answer: The length of third side is 24



Additional problems to solve geometry exam:


Additional problems to solve geometry exam are as follows:

1)The ratio of two supplementary angles is 12 to 6. Find the measure of each angle.

Solution:

Let measure of smaller angle = 12x, measure of larger angle = 6x.
12x + 6x = 180° (The sum of supplementary angles is 180°.)

18x = 180°

x = 10°
Then, 12x = 12(10°) and 6x = 6(10°).

So, 12x = 120° and 6x = 60° (by equating the given equation)

The angles have measures of 120° and 60°.
This is the solution for the given geometry example problem.

Geometry Terms and Definitions

Introduction to learning geometry terms and definitions:
Geometry is a branch of mathematics which  deals with the study of different shapes. Also learning the geometry terms and definitions include certain constructions of geometry such as lines, angles, plane etc., the word geometry is derived from the two words ‘geo’ meaning ‘earth’ and ‘metron’ meaning measuring. The geometry of plane figures are known as Euclidian geometry or plane geometry. I like to share this Skew Lines Examples with you all through my article.

Solving Geometric Angles

Introduction for solving geometric angles:

The figure which consists of two rays with the same starting point and the angle which can be formed by the two arms on either side of the initial point and it is the vertex angle .There are different types of angles which based on their measuring degrees. Now we are going to see about the solving of geometric angles.


Types of solving geometric angles:


The different types of solving geometric angles is given by,

Right angle

Acute angle

Obtuse angle

Straight angle

Complementary angle

Supplementary angle

Right angle:

A right angle whose measure is 90°, is called a right angle.
Acute angle:

An acute angle whose measure is less than 90° is called an acute angle.

30°, 60°, 70° etc are all acute angles.

Obtuse angle:

An Obtuse angle whose measure is greater than 90° is called an Obtuse angle

120°, 135°, 140° etc are all Obtuse angle

Straight angle:

A Straight angle whose measure is 180° is called a Straight angle

Complementary angle:

A complementary angle is nothing but the sum of two angles measures 90° are called complementary angles.

30°, 60° are complementary angles .

Supplementary angle:

A supplementary angle is nothing but the sum of the two angles which measures 180° are called Supplementary angles.

120°, 60° are Supplementary angles. I have recently faced lot of problem while learning geometry tutoring online free, But thank to online resources of math which helped me to learn myself easily on net.


Example for solving geometric angles:


Ex1:

A geometric angle is 14° more than its complement. What is its measure?

Sol:

Let x° be the required angle.

Its complement=90°-x°

By the given condition:

90°-x°+14°=x°

2x°=104°

X°=52°

Hence required angle=52°

Ex2:

The measure of an geometric solving angle is double the calculate of its supplementary angle. Find its measure.

Sol:

Let the required angle =x°.

Its supplementary angle =180°-x°

By the given condition =2(180°-x°)

=360°-2x°

=120°

Hence required angle=120°

Ex3:

The two supplementary angles are the ratio2:3.Find the angles .

Sol:

Let the two angles in degrees be 2x and 3x

By the given condition=2x+3x=180°

5x=180°

X=36°

Hence the required angles are 2×36°=72° and

3×36°=108°

The perimeter of a rectangle is 400 meters and its length is 3 times its width W. Find Width and Length, and the area of the rectangle.

Solution:

Use the perimeter formula to write.

2 L + 2 W = 400
"its length is 3 times its width W" into a mathematical equation as follows:

L = 3 W
We substitute L = 3 W in the equation 2 L + 2 W = 400.

2(3 W) + 2 W = 320
Expand and group like terms.

8 W = 400
Solve for W.

W = 50 meters
Use the equation L = 3 W to find L.

L = 3 W = 150 meters
Use the formula of the area.

Area = L x W = 150 * 50 = 7500 meters 2.

Geometry Questions

Introduction :

Geometry is a section in math, which deals with many aspects regarding shapes, figures. they involve with construction, study of their properties, area , volume, etc. They include study of solids too. Geometry deals with the entire concepts related to the shapes, solids, etc. Sample questions about the intersecting lines, area are in the following section.


Example geometry questions:


Here are few example geometry questions:

Geometry question 1:

Find the area of the triangle formed by (5,2), (-9,-3), (-3,-5)

Solution:

The formula for finding the area of the triangle formed by  (x1,y1), (x2,y2), (x3,y3)  is 1/2 | [x1(y2 – y3) + x2(y3 – y1) + x3(y1 – y2)] |

Applying the formula,we get

1/2 | [5(-3 + 5) -9(-5 -2) -3(2 + 3)]|

1/2 |10 + 63 – 15|

1/2 |58|

Hence the area of the triangle is 29.


Geometry question 2:

Find the point which divides the line segment joining (-1,2) and (4,-5) in the ratio 3:2

The formula for a point which divides the line joining A(x1,y1) and (x2,y2) in the ratio l:m is

`((lx2 + my1)/( l + m) ,(lx2 + my1)/( l + m)) `

Applying the formula,

The point is

`((3 * 4 + 2 * (-1)) /( 3 + 2) , (3 * (-5) + 2 * 2)/(3 + 2))`

`((10)/(5),(-11)/(5))`

Hence the point is (2,-11/5)
