Answer:
The two ways to represent proportion using table is
1.→ If difference between two y value, and two x values, represented as points in two dimensional plane yields a constant ratio, then it will be a Proportion.
For example
x 1 3 5 7 9
y 2 4 6 8 10
2.→If points are represented on a line, the ratio of two consecutive points produces a constant ratio,then we say that it is in Proportion.
2, 4, 8,16,32.

Answer:
The angle subtended by an arc at the center is double the angle subtended by it at any point on the remaining part of the circle.
Step-by-step explanation:
Let us consider the image attached.
Center of circle be O.
Arc AB subtends the angle on the circle and
on the center of the circle.
To prove:
Proof:
In : AO and PO are radius of the circles so AO = PO
And angles opposite to equal sides of a triangle are also equal in a triangle.
So,
Using external angle property, that external angle is equal to sum of two opposite internal angles of a triangle.
Similarly,
In : BO and PO are radius of the circles so BO = PO
And angles opposite to equal sides of a triangle are also equal in a triangle.
So,
Using external angle property, that external angle is equal to sum of two opposite internal angles of a triangle.
Now, we can see that:
Using equations (1) and (2):
Hence, proved.
