Answer:

Step-by-step explanation:

1. Cut six desired measures of string to properly wrap and tied around each end of the three sticks

2. Once fastened, bring two of the sticks together making one the bottom (base) and the other a side (angle).

3.Cut a tiny piece of rope to interlock with the rope you already have tied on the ends.

4.Tie the ends together with the new cut of string and make your desired angle as you tighten it.

5. Mirror Step 4 for the other end of the bottom stick (base), while most importantly mirroring the desired angle of step 4.

This should give you a proper equilateral triangle made out of sticks and string or anything of these two materials.

What is the general form of the equation of the line shown? Y-2=0 y+2=0 X-2 = 0

Tatiana [17]

Answer:Option A is correct.

y-2=0

Step-by-step explanation:

Option A is correct.

General form of the equation of the line: y-2 = 0

Step-by-step explanation:

The general form of the equation is given by:

y = mx +b where m is the slope and b is the y-intercept.

y-intercepts of the line is the value of y at the point where the line crosses the y-axis(i.e x= 0)

From the given figure;

we can see that the line crosses the y-axis at y =2 and also here the slope is , m= 0

therefore, by definition of y-intercepts

y-intercept (b) = 2

Therefore, the equation of line as shoen in figure is:

y = (0)x + 2

y = 2

y-2 = 0

Therefore, the general form of the equation line as shown in the figure is:

y-2 =0

The condition_______?proves that ∆ABC and ∆EFG are congruent by the SAS criterion.

snow_lady [41]

Answer:

(1) D.Angle C is congruent to to Angle F. (2) C. SSS. (3) C. cannot be congruent to.

Step-by-step explanation:

From the given figure it is noticed that

$AC=EG$

$CB=GF$

According to SAS postulate, if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then both triangles are congruent.

The included angles of congruent sides are angle C and angle G.

So, condition "Angle C is congruent to to Angle F" will prove that the ∆ABC and ∆EFG are congruent by the SAS criterion.

If $AB\neq EF$

According to SSS postulate, if all three sides in one triangle are congruent to the corresponding sides in the other.

Since two corresponding sides are congruent but third sides of triangles are not congruent, therefore SSS criterion for congruence is violated.

Since two corresponding sides are congruent but third sides of triangles are not congruent, therefore the included angle of congruent sides are different.

$\angle C\neq \angle G$
