Question

show that the points (1, -6) (5, 2) (7, 0) (-1, -4) are concyclic
​

Answer 1

Answer:

you have to plot this point on graph and it will form a quadiletral and measure it all angles

Answer 2

Answer:

Here points (1, -6) (5, 2) (7, 0) (-1, -4) from a quadrilater when we plots it on graph paper.

We can see that the sum of angles is 360°.

Therefore it is a quadrilater.
