Plot A(2,9), B(7,9), C(−3,−5), and D(−3,1) in a coordinate plane. Are AB and CD congruent? if you answer before 11:59 you get brainliest

Given :

Four points A(2,9) , B(7,9) , C(-3,-5) and D(-3,1) .

To Find :

Are AB and CD congruent .

Solution :

Two line segment are congruent when their length is equal .

Now , length of line segment with points  (a,b) and (c,d) .

.

So , length of AB is :

Also , length of CD is :

Since , length of AB and CD is not equal .

Therefore , the line segment AB and CD are not congruent .

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

m∠a is 90°

m∠b is 40°
