Answer:

Combine points A with C and A with B. Consider ΔABD and ΔACD:


1. AD is common side, then  AD\cong AD;


2.   CD\cong BD  - given in the diagram;


3.  \angle ADB\cong \angle ADC .


By SAS Postulate,  \triangle ABD\cong \triangle ACD . Congruent triangles have congruent corresponding sides and congruent corresponding angles, so  AC\cong AB .


From this proof you can see that correct choice is option D (In triangles ABD and ACD, two sides and an included angle are equal.)

Choose the number sentence that shows the distributive property of multiplication over addition.
Anarel [89]

we know that

distributive property of multiplication over addition:

a \times (b+c)=a \times b + a \times c

now, we will verify each options

option-A:

3 × (4 + 5) = (3 × 4) + (3 × 5)

We can see that both sides match with property

so, this is TRUE

option-B:

3 × (4 + 5) = (3 + 4) × (3 + 5)

We can see that right side does not match with property

so, this is FALSE

option-C:

3 × (4 + 5) = (3 × 4) + 5

We can see that right side does not match with property

so, this is FALSE
