Which series of transformations shows that triangle A is congruent to triangle B? A.
Reflect triangle A over the y-axis, rotate it 180° about the origin, and translate it 5 units up and 2 units to the right.

B.
Rotate triangle A 90° counterclockwise about the origin, reflect it over the x-axis, and translate it 3 units to the left.

C.
Reflect triangle A over the y-axis and translate it 2 units up.

D.
Reflect triangle A over the x-axis, translate it 5 units to the right, and reflect it over the y-axis.

answer: idk

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

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.

show us the triangle so we can answer it
