The parallelogram shown below has an area of 35 units^2 2 squared. Find the missing height. h =h=h, equals units
Anit [1.1K]

Answer:

h = 5 units

Step-by-step explanation:

Given that,

The area of the parallelogram, A = 35 unit²

In the attached figure, we can see that the base is 7 unit.

We know that,

Area of a parallelogram, A = b × h

So,

h=\dfrac{A}{b}\\\\h=\dfrac{35}{7}\\\\h=5\ units

So, the value of h is equal to 5 units.

reflection symmetry is the quality a design has if it maintains all characteristics when it is rotated about an axis lying in it
OlgaM077 [116]

Answer:

True if reflection over a line.

Step-by-step explanation:

Given that there is a reflection symmetry. We have to discuss about the quality of the design.

By reflection , we mean it can be either on a line or on a point.

If symmetry is on a line, then we get a mirror image of the original one keeping the line of symmetry as mirror.  Hence in this case when rotated about axis of symmetry lying it its plane the original design would be maintained.

Examples are : Circles, ellipses, hyperbolas, etc.

Reflection about a point is obtained by keeping equal distance form the point.

For example, reflection of (1,1) over origin would be (-1,-1)

Here the rotation quality may not apply
