How can you show that a triangle has three congruent sides?
algol [13]
There are 4 rules for congruent triangles:

SSS-->This means side,side,side and to prove triangles are congruent with this rule, all the sides will be the same on both triangles.
SAS-->This means side,angle,side and to prove triangles are congruent, you must have 2 sides and an angle the same on both triangles, but the angle MUST be in between the 2 sides.
ASA-->This means angle, side, angle and to prove triangles are congruent with this rule, you must have two angles and a side the same, but the side MUST be in between the two angles.
RHS-->This means right angle, hypotenuse, side and to prove triangles are congruent with this rule, you must have a right angle in both triangles, and have an equal hypotenuse and side.

Hope this helps:)

If x - 12y = -210 and x - 6y = 90, then x =
Annette [7]
X=-198(substitute the value of x into the equation)
x-6y=90

-198-6y=90(solve the equation)

y=-48(a possible solution is)

(x,y)=(198,-48). (check yhe solution)

-198-12= 210(simplify)
-198-6(-48)=90

-210=-210( the ordered pair is a solution)
90=90

(x,y)=(198,-48)
is the answer
