List the 6 congruency statements given ABC = DEF
galina1969 [7]

Answer:

∠A ≅ ∠D, ∠B ≅ ∠E, ∠c ≅ ∠F, AB = DE, BC = EF, AC = DF

Step-by-step explanation:

Given that triangles ABC and DEF are congruent. Now we need to choose correct congruency statements from the given choices.

We know that corresponding angles of congruent triangles are equal so we can write:

∠A ≅ ∠D

∠B ≅ ∠E

∠c ≅ ∠F

We know that corresponding sides of congruent triangles are equal so we can write:

AB = DE

BC = EF

AC = DF

comparing these with given choices we see that, First choice is correct.

serg [7]

Answer:

h = 40.5 m

A) 1 : 9

B) 1 : 3

C) 40.5 m

Step-by-step explanation:

Let the height of the larger triangle be h

Therefore,

\frac{10}{90}= \frac{4.5}{h}\\\\\frac{1}{9}= \frac{4.5}{h}\\\\h = 9\times 4.5\\\\h = 40.5\:m\\

A)

The ratio of the area of small triangle to the large triangle

=\frac{10}{90}=\frac{1}{9}=1 : 9

B)

The ratio of the side length of small triangle to the side length of large triangle

=\sqrt{\frac{10}{90}} =\sqrt {\frac{1}{9}} =1 : 3

C) The height of the larger triangle is <u>40.5 m</u>

Find the linear equations written in standard form. Select all that apply. A. x+y=-1 B. -3x = y C. x + 4y = 0 D. y = 5x - 2 E. x
Valentin [98]
<h3>3 Answers: A, C, and F</h3>

All of these equations are in the form Ax+By = C

  • An equation like x+y = -1 has A = 1, B = 1, C = -1
  • An equation like x+4y = 0 has A = 1, B = 4, C = 0
  • An equation like 8x-3y = 20 has A = 8, B = -3, C = 20
