Answer:
Two angles that have the same measure are called congruent angles. Here are two angles that both measure 30°. We say that angle x is congruent to angle y.

Answer:

Step-by-step explanation:
Given
Co ordinates of vertices(1,-6) and (-8,-6)
When two points is given then Length of two points is given by



Perimeter of rectangle is =26 units
Let the other side be x
thus

x+9=13
x=4 units
therefore to get the other two co ordinates
such that the length of that side is 4 units is


Horizontal distance will remain same only vertical distance will change in given co ordinates to obtain the remaining two co ordinates
To verify the above two distance between two points must be 13 units
Y is less than or equal to -16 i think but I’m not sure
