Answer:

The figures are congruent

see the explanation

Step-by-step explanation:

we know that

If two figures are congruent, then its corresponding sides and its corresponding angles are congruent

In this problem

Triangles A.B.F and E.D.C are congruent

because

A.B≅E.D

A.F≅E.C

B.F≅D.C

and

∠A≅∠E

∠B≅∠D

∠F≅∠C

The three sides and three interior angles of triangle A.B.F are congruent to the three sides and three interior angles of triangle E.D.C

Remember that

If two triangles have two equal angles, then the measure of the third angle must be equal

Mrs. Ruiz has 11/12 yard of string to hang 3 banners. She uses the same length of string to hang each banner. How much string do

lesya [120]

Answer:

$\frac{11}{36}$ yard

Step-by-step explanation:

Length of string Mrs. Ruiz has = $\frac{11}{12}$ yard

Mrs. Ruiz needs to hang 3 banners using the string.

Having known that each banner uses same length of string to be hung we can divide total length of sting into 3 equal parts.

So, we can divide $\frac{11}{12}$ yard by 3 as

⇒ $\frac{11}{12}\div 3$

Changing the division sing to multiplication by taking reciprocal of divisor.

⇒ $\frac{11}{12}\times \frac{1}{3}$

We can now multiply numerators and denominators.

⇒ $\frac{11}{36}$ yard

∴ Mrs. Ruiz must used $\frac{11}{36}$ yard of string for each banner.
