Question

A quadrilateral has vertices A{11, -7), B(9,-4), C11,-1), and D(13,-4).

Answer 1

Answer:

Quadrilateral ABCD is a parallelogram

if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a kite

Step-by-step explanation:

without solving, im guessing that quad ABCD is a paralellogram (//gram)

lets test this theory

see if the slope of AB and CD, and BC and AD is the same

slope AB and CD

AB:

-7--4/11-9

=-3/2

CD:

-1--4/11-13

=3/-2

=-3/2

slope is the same

slope BC and AD

BC:

-4--1/9-11

=-3/-2

=3/2

AD:

-7--4/11-13

=-3/-2

=3/2

slope is same

because 2 pairs // sides ---> //gram

if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a kite

hope this helps!
