In question 8, we're going to be considering two lines, a, b and c, d, that intersect at e.
00:06
Now we're going to be telling which of their transformations can be used to show that angle a, angle a, e, d, is congruent to angle b, a, c.
00:30
Okay, so let's start.
00:32
Now the first one is a 90 -degree counterclockwise rotation about e.
00:37
Now if we perform a 90 degree counter clockwise rotation, it's not going to fit onto this.
00:43
So that's not what we're looking for.
00:47
Next, a reflection across ab.
