I love this unit a-lot (super fun)
So Congruent/Congruence is, For example If you have two triangles on a coordinates grid with the same coordinates than that would mean they're congruent. Shortened down would be
Same shape same coordinates same dimension same size (same everything)
Transformations would be Rotating a shape clockwise(CW)...right) or counterclockwise(CC Left)
Or Dilation which is making the shape smaller or bigger based on a scale factor.
Or reflection
How you would perform Reflection is reflect the shape over either the X-axis
Or the Y-axis
How you would perform a Translation would be to literally move the shape right left up or down.
How you would perform a Dilation(scaling) would be to pick a scale factor and either decrease or increase the size of the shape according to the scale factor number
How you would perform a Rotation would be to pick a point of rotation (P.O.R) and then pick your measure º such as 90º clockwise and rotate accordingly.
Hope it helps :)
Okay, so I really hope that you can read all my work. I just spent the last 45 mins doing this problem as neatly as possible with as much detail as possible. So, I really hope my work doesn't confuse you.
My Final Answers were:
JI= 40 units (found using the Pythagorean theorem)
IM= 66.66 units = 66 and 2/3rds (found by dividing the length of JL by the cosine of ∠JIM )
LM=42.66 units = 42 and 2/3rds (found by IM= 24+LM; solve for LM since we know IM=66.66)
JM= 53.33 units= 53 and (1/3rd) (found by using the Pythagorean theorem; this time using JI as "a" and IM as c)
Hope this helped and all made sense!
(Pythagorean theorem is a²+b²=c²)
Overtime, weather can shape our land in ways such as water levels rising or ice melting. Heat that is in the earth's molten core can over time cause lands to move (ex. Continental drift) and much more. Water levels are a problem mainly because of the rapid human population growth rate. In the future, weather could change the way that we live our lives.
