Answer:
a) J':(-7,7) K':(-5,2) L':(-2,3)
b) The x coordinates remained the same, the y coordinates swapped from negative to positive.
Step-by-step explanation:
Aside: I'm using J', K', and L' to denote the new locations of J,K,L after the reflection.
When an object is reflected over the x-axis, it means it's positive points will flip to negative y space, and negative points will flip to positive y space.
That said, J, for instance, will have the same X-coordinate, but its Y-coordinate will flip from negative to positive. Doing this with every vertex mirrors the triangle over the X-axis.
Therefore, J:(-7,-7) will become J':(-7,7), and likewise with K and L becoming K':(-5,2) and L':(-2,3).
The sum of interior angles of a triangle must add up to 180 degrees
if the triangle has an angle that is greater than 90 degrees, then it is considered obtuse
if the triangle has an angle that is 90 degrees, then it is considered right
if all angles are less than 90, then it is acute
find the missing angle "x"
180=60+80+x
is angle x less than, greater, or equal to 90 degrees?
