Answer:
2.
Step-by-step explanation:
Rotating a figure about the midpoint of its diagonal, the figure will coincide with its pre-image two times: at 180° and at 360°.
This is different than rotating about the origin; for a rotation about the origin, a 180° rotation does not always coincide with the pre-image.
hope that answers ur question :))))
Answer:
Congruent angles have the same angle.
Answer:
30
Step-by-step explanation:
130 + 20 = 150
All angles added together in a triangle equal 180 so...
180 - 150 = 30
I hope this helps!
Answer: 3 weeks
Step-by-step explanation: One=4
Second week=8. Bc 4+4=8
third week= 12. Bc 8+4=12
Answer:
a. 
b. 
Step-by-step explanation:
The given point is
.
We want to find the image after this point has been reflected in the line
.
Recall that, the mapping for a reflection in the line
is
.
This implies that,
.
This simplifies to,
.
This will finally give us,
.
b. We now apply the second reflection, which is a reflection in the line
.
Recall again that, the reflection in the line
has the mapping
.
This implies that,
.
This implies that,
.
This will finally give us,
.
