Statement 1: angle K = angle N

Reason 1: Given

-----------------

Statement 2: segment LM bisects angle KLN

Reason 2: Given

-----------------

Statement 3: Angle KLM = angle NLM

Reason 3: Definition of angle bisector

-----------------

Statement 4: LM = LM

Reason 4: Reflexive property of congruence

-----------------

Statement 5: Triangle KLM = Triangle NLM

Reason 5: AAS congruence theorem

-----------------

Statement 6: LK = LN

Reason 6: CPCTC

-----------------

note: CPCTC stands for "corresponding parts of congruent triangles are congruent". Its like saying "those two houses are identical, so the front doors must be the same". In this analogy, the houses represent the triangles while the front doors represent the side lengths. If we know both triangles are the same, then the corresponding matching pieces must be the same as well (otherwise the triangles would be different).

see the attached image below for how the proof would look in a table format.

kifflom [539]

Answer:

13.03

Step-by-step explanation:

7 x 7 = 49

11 x 11 = 121

121 + 49 = 170

The square root of 170 is 13.03

Hope this helped!

The diagonals of a rhombus are 14 and 48cm. Find the length of a side of the rhombus.
FromTheMoon [43]

Step-by-step explanation:

Let ABCD be a rhombus. So, AC (AC = 14 cm) and BD (BD=48 cm) will be its diagonals. Let us assume that diagonals are intersecting at point O.

Since, diagonals of a rhombus are perpendicular bisector.

\because \: OA  =  \frac{1}{2}  \times AC \\  \\   \therefore \: OA  =  \frac{1}{2}  \times 14 \\  \\   \huge \red{ \boxed{\therefore \: OA  =  7 \: cm}} \\  \\ \because \: OB  =  \frac{1}{2}  \times BD \\  \\ \therefore \: OB  =  \frac{1}{2}  \times 48 \\  \\ \huge \red{ \boxed{\therefore \: OB  = 24 \: cm}} \\  \\ In \:  \triangle OAB, \:  \:  \angle AOB=90° \\  \therefore \: by \: Pythagoras \: Theorem \\ AB= \sqrt{OA^2 +OB^2 }  \\  =  \sqrt{7^2 +24^2 } \\ =  \sqrt{49+576 } \\ =  \sqrt{625 } \\  \huge \orange{ \boxed{\ \therefore \:AB= 25 \: cm.}}

Hence, length of a side (or all) is 25 cm.

A triangular prism is 20 millimeters long and has a triangular face with a base of 24 millimeters and a height of 16 millimeters
uysha [10]

Answer:

The surface area of the prism is 1,664\ mm^{2}

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to

SA=2B+PL

where

B is the area of the triangular face

P is the perimeter of the triangular face

L is the length of the triangular prism

<em>Find the area of the triangular face B</em>

B=\frac{1}{2}(24)(16)= 192\ mm^{2}

<em>Find the perimeter of the triangular face P</em>

P=(24+20+20)= 64\ mm

we have

L=20\ mm

substitute the values

SA=2(192)+(64)(20)=1,664\ mm^{2}
