A) Describe the congruence shortcut (postulate/theorem) that could be used to prove that ΔABC≅ΔDEF

bixtya [17]

Answer:

A. By the Side-Side-Side (SSS) Congruence Theorem, ΔABC ≅ ΔDEF.

B. $\overline{AB} \cong \overline{DE}$

$\overline{BC} \cong \overline{EF}$

$\overline{AC} \cong \overline{DF}$

Step-by-step explanation:

a. From the diagram given, it shows that all three sides of ∆ABC are congruent to all the three corresponding sides of ∆DEF.

Therefore, by the Side-Side-Side (SSS) Congruence Theorem, ΔABC ≅ ΔDEF.

b. The sides that are congruent in the ∆s given that applies to the SSS Congruence Theorem are:

$\overline{AB} \cong \overline{DE}$

$\overline{BC} \cong \overline{EF}$

$\overline{AC} \cong \overline{DF}$

What two ratios are equivalent to 10:18

Whitepunk [10]

10 : 18 2 into 10 is 5, 2 into 18 is 9.

5 : 9.

You can also choose to multiply 10 : 18 by 2.

2*10 : 2*18

20 : 36.

Therefore 5 : 9 and 20 : 36 are two ratios that are equivalent to 10 : 18.
