A composition of transformations maps ΔXYZ to ΔX"Y"Z". Triangle X Y Z is reflected across the line of reflection m to form triangle X prime Y prime Z prime. Triangle X prime Y prime Z prime is rotated 90 degrees about point X prime to form triangle X double-prime Y double-prime Z double-prime.

The first transformation for this composition is [], and the second transformation is a 90° rotation about point X'.

a 180° rotation about point X
a 270° rotation about point X
a translation to the right
a reflection across line m

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
