Graph a triangle (STU) and reflect it over the y-axis to create triangle S’T’U’. describe the transformation using words. draw a line segment from point S to the reflecting line, and then draw a line segment from point S’ to the reflecting line. what do you notice about the two line segments your drew? do you think you would see some characteristics if you drew the line segment connecting T with the reflecting line and then T’ with the reflecting line? how do you know?

Step-by-step explanation:

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
