Answer:
x =
Step-by-step explanation:
The segment from the vertex to the base is a perpendicular bisector.
Using Pythagoras' identity on the right triangle on the left.
x² = 2² + 3² = 4 + 9 = 13 ( take the square root of both sides )
x =
Simplify the expression. 16 x 4 -4

HIJK is a parallelogram because the midpoint of both diagonals is
(1 , 0), which means the diagonals bisect each other
Step-by-step explanation:
If (x , y) is the mid-point of a segment whose end points are and
then,
In a parallelogram, its diagonals intersect each other at their mid-points
that means its diagonals bisect each other
∵ HIJK is a quadrilateral
∵ HJ and IK are its diagonals
∵ H = (-2 , 2)
∵ J = (4 , -2)
- Find the mid point of HJ
∵
∴
∴
∴ The mid-point of HJ is (1 , 0)
∵ I = (4 , 3)
∵ K = (-2 , -3)
- Find the mid point of IK
∵
∴
∴
∴ The mid-point of IK is (1 , 0)
∵ The mid-points of HJ and IK are equal
∴ HJ and IK bisects each other
∴ HIJK is a parallelogram because its diagonals bisect each other
HIJK is a parallelogram because the midpoint of both diagonals is
(1 , 0), which means the diagonals bisect each other
