Question

ABCD is a quadrilateral,side BC is produced to F and the side AD is produced to E find the measures of angles x and y

Answer 1

Answer:

In first quadrant X and Y coordinate are positive,in second quadrant X is negative and Y is positive,In third quadrant X and Y are negative, in fourth quadrant X is positive and Y is negative. For a point in the horizontal plane X coordinate is zero and for a point in the vertical plane Y coordinate is zero.

Step-by-step explanation:

Signs of the abscissa and ordinate of a point in the second quadrant are respectively:

= The signs of the x and y co-ordinates in the 4 quadrants are as tabulated below:

Quadrant x y

I + +

II − +

III − −

IV + −

From the table, it can be observed that in the second quadrant, x is negative and y is positive hence the coordinates of a point in the second quadrant will have sign of the form (−,+).
