<span>Rigid motion of a plane is a transformation where the original and new image are congruent. In short, it's also known as isometry.
In the case above, ΔDWP is presumed to be congruent to </span><span>ΔMJS. Rigid motions involved here are translation and rotation.
In translation, you are basically sliding/moving the figure. </span>ΔDWP is moved five (5) units down then one (1) unit to the left. Thereby, coinciding point W of ΔDWP and point J of ΔMJS.<span>
Next rigid motion used is rotation. The figure is simply rotated approximately 90 degrees thereby coinciding all points of </span>ΔDWP to ΔMJS<span>.
To check for congruency by just merely looking on the plane, compare the lengths of the sides of the triangles.
side DW = side MJ = 2 units
side WP = side JS = 4 units
side PD = side SM = 5 units
Therefore, we can say that </span>ΔDWP is congruent to ΔMJS.<span>

Answer:
angle 2 = 22°
Step-by-step explanation:
When added together, angles 1 and 2 equal angle ABD.
Thus, angles 1 and 2 added together results in 109°.
Represent angle 1 as angle 2 plus 65°.
Our equation then becomes angle 2 + 65° + angle 2 = 109°.
Subtracting 65° from both sides, we get: 2·angle 2 = 44°.
Dividing both sides by 2 results in:
angle 2 = 22°
The best estimate would be 35%.
7 out of the 20-coin sample were from before 1980; 7/20 = 35%.
Answer: 14 times
Step-by-step explanation:
45 - 10 = 35
35/2.5 = 14
