Claudia drew quadrilateral ABCD on a coordinate grid and measured all the side lengths and angle measurements of the quadrilateral. Then, she dilated quadrilateral ABCD by a scale factor of ½, centered at the origin and labeled that quadrilateral WXYZ. Which of the following characteristics must be true about quadrilaterals ABCD and WXYZ? Select all that are true. A
Quadrilaterals ABCD and WXYZ are similar shapes.
B
Quadrilaterals ABCD and WXYZ have the same side lengths.
C
Quadrilaterals ABCD and WXYZ have the same angle measurements.
D
The ratio of the side lengths of quadrilaterals ABCD and WXYZ are the same.
E
Quadrilaterals ABCD and WXYZ have the same orientation.
F
Quadrilaterals ABCD and WXYZ have the same perimeter and area.

its d. the first coordintaes are 10,32

step-by-step explanation:

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.

step-by-step explanation:

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
