Which statement listed below illustrates the reflexive property of congruence

Vlad1618 [11]

Option D:

$\triangle K L M \cong \triangle K L M$

Solution:

Reflexive property of congruence:

<em>Reflexive property of congruence means the geometric figure is congruent to itself.</em>

Option A: If $\triangle K L M \cong \triangle P Q R \text { and } \triangle P Q R \cong \triangle S T U \text { , then } \triangle K LM\cong \triangle S T U$

From the definition of reflexive property, it is not true.

This is transitive property of congruence triangles.

Therefore it is false.

Option B: $\text { If } \triangle KL M \cong \triangle P Q R \text { , then } \triangle P Q R \cong \triangle S T U \text$

From the definition of reflexive property, it is not true.

Therefore it is false.

Option C: $\text { If } \triangle K L M \cong \triangle P Q R \text { , then } \triangle P Q R \cong \triangle K L M$

From the definition of reflexive property, it is not true.

Therefore it is false.

Option D: $\triangle K L M \cong \triangle K L M$

Here, ΔKLM is congruent to itself.

This statement illustrates the reflexive property of congruence for triangles.

Therefore, it is true.

Hence option D is the correct answer.

The length of a rectangle is three more than twice the width. The perimeter is 96. What are the dimensions?

SIZIF [17.4K]

Answer:

Width =15

Length =33

Step-by-step explanation:

Take width as x

And length as 2x+3

Perimeter as 96

Formula of the perimeter of a rectangle is 2l+2w

X+×+2×+3+2×+3=96

6x+6=96

6x=96-6

6×=90

X=15

Width =x and x =15 so width =15 while length =33

Solve the equation by the zero factor property 6x^2 -5x -6=0

Alex_Xolod [135]

First, you need to factor the polynomial.

I'll use the trial and error method.

6x^2 - 5x - 6 = 0

6 has factors
6 and 1
3 and 2

I'll try 3 and 2 first.

(3x     )(2x      ) = 0

Now we need to factor -6.
-6 factors into
-1, 6
-6, 1
-2, 3
-3, 2

Now we need to see if one of these pairs of factors placed correclty will factor the trinomial.

(3x + 2)(2x - 3) = 0

That did it.

Now we use the zero factor property.

3x + 2 = 0 or 2x - 3 = 0

3x = -2      or 2x = 3

x = -2/3     or x = 3/2

The ratio of the angles of a triangle is 5:2/3:1. what are the measures of all three angles

Art [367]

The ratio of the angles of a triangle is 5: 2/3: 1 Then the measure of all three angles are 135, 18, 27 respectively.

<u>Solution:</u>

Given that, the ratio of the angles of a triangle is $5: \frac{2}{3}: 1$

We have to find what are the measures of all three angles.

Let us suppose, "x" is the highest common factor of three angles.

Then, the three angles will be $5x, \frac{2}{3}x, x$

Now, we know that, sum of angles of a triangle equals to 180

$\text { Then, } 5 x+\frac{2}{3} x+x=180$

$\begin{array}{ll}{\rightarrow} & {6 x+\frac{2}{3} x=180} \\\\ {\Rightarrow} & {x\left(6+\frac{2}{3}\right)=180} \\\\ {\Rightarrow} & {x\left(\frac{6 \times 3+2}{3}\right)=180} \\\\ {\Rightarrow} & {x\left(\frac{18+2}{3}\right)=180} \\\\ {\Rightarrow} & {x \times \frac{20}{3}=180} \\\\ {\Rightarrow} & {x=180 \times \frac{3}{20}} \\\\ {\Rightarrow} & {x=9 \times 3=27}\end{array}$

So, the three angles will be,

$5x = 5 \times 27 = 135\\\\\frac{2}{3} \times 27 = 18\\\\x = 27$

Hence, the angles of the triangle are 135, 18, 27 respectively.
