Answer:

Step-by-step explanation:
Area of a rhombus is the product of the length of the diagonals divided by two.
Length of one diagonal is 8 units and the other diagonal is 16 units
Area is given by

The area of the rhombus is 
Another approach is the diagonals have created 4 triangles where the base and is height is either 4 units long or 8 units long so the area of the rhombus would be the area of the 4 triangles.

Answer:
SSS
Step-by-step explanation:
Well, the picture says asks why the triangles are congruent but your question asks why they aren't congruent, so I will just assume that you made a typo, and you really meant: "Which rule explains why these triangles are congruent?"
Well, the triangles have two congruent sides, and they have a common shared side that are both congruent (due to reflexive property), so the triangle theorem SSS (Side-Side-Side) proves that the triangles are both congruent.
I’m not sure but if you go on jigga math and type this answer in people will answer
Answer:
9
Step-by-step explanation:
We can set up a systems of equations to find the value of the third side.
Let's assume that
is the length of both sides 1 and 2. Let's also assume that
is the length of the third side.
We know that
, and looking at the first clue we can make the equation
.
We can substitute y into the equation
.

So the length of the side that is the same as the second is 7.
Now we can plug this into the equation
to find
.

Hope this helped!
Answer:
<em>18cm</em>
Step-by-step explanation:
Perimeter of triangle= a+a+a (side + side+ side)
Perimeter of triangle= 6 cm+6cm+6cm
Perimeter of triangle= 18cm
