Answer:
Both ΔABC and ΔDEC are congruent, therefore there a rigid transformation that would map ΔABC to ΔDEC.
Step-by-step explanation:
In rigid transformation the size and shape of the figure remain s the same if the original figure and transformed figure are congruent.
In ΔABC and ΔDEC,
(Given)
(Given)
(Given)
By AAS postulate of congruent triangle,
Since both ΔABC and ΔDEC are congruent, therefore there a rigid transformation that would map ΔABC to ΔDEC.
The diagram shows the 180 degree rotation about the point C and the rotation is a rigid transformation.
Answer:
A letter T is folded vertically through the middle.
Step-by-step explanation:
Reflectional symmetry refers to the symmetry of line that divides the given shape into two equal halves. The halves represent the mirror reflection of each other. The line of symmetry is drawn to show the reflection and it acts as a mirror. For the letter 'T', the reflectional symmetry will be drawn vertically in the middle of the letter. The line divides the letter into two equal halves with mirror images.
The coordinates of the original quadrilateral are (1, 2), (4, 2), (1, 4), and (4, 4). After transformation, the new coordinates are (1, −2), (4, −2), (1, −4), and (4, −4). Thus, as we can see, the y coordinates of the original points have been multiplied by-1. This happens only when there is a reflection about the x axis.
Thus, the type of transformation in question here is reflection about the x axis.

Answer:
you turn the feet into inches and then add them together.
Example 1 ft = 12 inches + 5 inches = 17 inches
