4) use the figure below to answer parts a and b. show your work. (4 points) a.)explain, in words, a series of rigid motions that would map ∆mjs onto ∆dwp. b.)write the ordered-pair rule for each transformation in the sequence

Part A:

The series of rigid motions that would map ∆MJS onto ∆DWP are:

a.) A rotation of 90 degrees about the point J in the clockwise direction.
b.) A translation of 1 units to the right and 5 units up.

Part B:

The ordered-pair rule for each transformation in the sequence are:

a.) R (J, 90 degrees)
b.) (x, y) → (x + 1, y + 5)

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
