Which triangles are congruent by SAS?
boyakko [2]

Answer:

Option A

Triangles ABC and TUV

Step-by-step explanation:

Given three triangles ABC , FGH and TUV

For triangles ABC and FGH, given that

DF =AB

DH = AC

and angle F = angle A

This cannot be taken as SAS congruence because the angle F is not included between the equal sides.  Two triangles can be congruent by SAS only if two sides and included angle are congruent.

For triangles ABC and TUV we have AB=TU, AC = TV and

included angles between these sides are equal.

So these two triangles are congruent

We write corresponding sides only in order Hence ABC = TUV

and Not VTU =ABC

So option A is true.

What steps should be followed to solve the inequality -4x < 8.
marishachu [46]

Answer:

The require step to solve the inequality

-4x < 8 is

Divide by -4 on each side and flip the sign.

\therefore x

Step-by-step explanation:

What steps should be followed to solve the inequality

-4x < 8

Solution:

-4x < 8

Divide by -4 on each side and flip the sign.

So the equation becomes

\dfrac{-4x}{-4}> \dfrac{8}{-4}\\ \\

Now minus 4 will get cancel from left and side and in right inside -2 will be there such that (flip the sign)

\dfrac{x}{1}> \dfrac{-2}{1}\\\\\therefore x>-2
