Constructed Two Dimentional Figure

A.    Constructed two dimentional figure

1.      Congruent two build flat (same and contruct)

1.2  Mirroring the rhombus ABCD by line l

-          The corresponding angels are equal

-          The corresponding sides (lay) are the same length.

2.      Two dimentional construc figure

        

a.       The corresponding angles are equal.

b.      The corresponding sides (plot) are comparable.

3.      Calculating the Side  Length and the Large Angle of Two dimentional  figure

a.       Side Length and the large angle congruent dimentional

1.      The corresponding angles are equal

2.      The corresponding sides are the same length

b.      Side Length and the large angle construct dimentional

B.     Congruent Triangles

1.      Congruent Two Triangle Terms

conclude that two triangles are said to be congruent if and only if they have the same shape and size. If so, the scattered elements close together perfecly.

2.      Internals of Congruent Two Triangle

a.       Tree Sides (S-S-S)

If two triangles are congruent, then the three sides of the first triangle are equal to the three sides of the second triangle (the sides of the square).

b.      Two Sides and One Angle Apit (S-Sd-S)

Two Congruent triangles, then the two sides of the first triangle are equal to the two sides of the second triangle, and the angles that are flanked are equal.

c.       Two Angles and One Side (Sd-S-Sd)

Two Congruent triangles, then the two sides of the first triangle are two angles in the second triangles, and the sides between the two angles are equal.

3.      Comparison of the sides of two congruent triangles

If two triangles are congruent, then the sides that are in front of the same angle have the same length. Comparison of the sides of the first triangle is the same as the comparison of the sides of the second triangle.

C.     Constructed Triangles

1.      Constructed Two Triangles Terms

    

Figure 1.7 :ABC PQR

∆   ABC ~ ∆ PQR so that the conditions of congruence apply, namely:

a. Cracked angles are equal.

b.    The sides are proportionally eequal

2.      Internals of Constructed Two Triangles

a.       Comparable Sides

Conclution

In two congruent triangles, the corresponding sides are equal or sides (S-S-S)

b.      Angles equally large (Sd-Sd-Sd)

Conclution

In two congruent triangles there are two corresponding angles equal

c.       One Same Angle and Both Sides Flanking Comparable (S-Sd-S)

Conclution

In two comparable triangles there is one angle that is equal to the two sides that flank it equally.

3.      Comparison of the side of two triangles construct

a (c + d) = c (a + b)

ac + ad	= ca + cb
ac + ad - ac	= ac + bc - ac
ad	=  bc

A model / design of an aircraft with a scale of 1: 300. If the actual length of the aircraft is 60 meters and the distance between the two wing tips is 18 meters, determine the measurements in the model / design

Answer :

For example the length of the plane in the design = x Distance of the two wing tips = y

 

300 x = 6000

x = 

x = 20

y = 6

So, The length of the plane in the design is 20 cm and the distance of the two wing tips is 6 cm.

Given two rectangles ABCD and the PQRS rectangle as shown below.

The two rectangles are congruent. Determine:

a) PQ length

b) area and round of the rectangle of the PQRS

Answer :

a) Comparison of the length of lines AB and AD corresponds to the length of the line PQ with PS. Permanent

PQ = 24 cm long

b) Square length PQRS   = PQ x PS

= 24 cm x 6 cm = 144 cm²

Square around of PQRS = 2 x (PQ + PS)

= 2 x (24 cm + 6 cm)

= 60 cm
