The given parallelogram is a rhombus
Solution:
Option A: Rhombus
Let us recall the property of rhombus.
- Diagonals bisect each other at right angles.
- Opposite angles are congruent.
Here diagonals bisect the angles equally each 72°.
Opposite angles are congruent(72° + 72° = 144°).
Hence the given parallelogram is a rhombus.
Option B: Rectangle
Let us recall the property of rectangle.
- Diagonals bisect each other.
- All the angles of a rectangle are 90°.
Here 72° + 72° = 144°, not 90°.
So, the given parallelogram is not a rectangle.
Option C: Square
Let us recall the property of square.
- Diagonals bisect each other.
- All the angles of a square are 90°.
Here 72° + 72° = 144°, not 90°.
So, the given parallelogram is not a square.
Answer:
x = 4
y = 1
Step-by-step explanation:
use one equation to solve for one variable.
y = 5 - x
Now plug the value of y in the other equation
x - (5-x) = 3
x+x= 3+5
2x=8
x=4
Now use the value of x to find the value of y on the first equation
y = 5 - x
y = 5 - 4
y = 1
