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.

What is the least common denominator of 9,8,6,5
Alex

Answer:

1

Step-by-step explanation:

LCD = 1

Equivalent Fractions with the LCD

9 = 9/1

8 = 8/1

6 = 6/1

5 = 5/1

Solution:

Rewriting input as fractions if necessary:

9/1, 8/1, 6/1, 5/1

For the denominators (1, 1, 1, 1) the least common multiple (LCM) is 1.

LCM(1, 1, 1, 1)

Therefore, the least common denominator (LCD) is 1.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

9 = 9/1 × 1/1 = 9/1

8 = 8/1 × 1/1 = 8/1

6 = 6/1 × 1/1 = 6/1

5 = 5/1 × 1/1 = 5/1
