When figures are translated, rotated or reflected, the resulting figures are congruent to the original figure because the transformations are rigid. However, when a figure is dilated, the resulting figure is not congruent to the original figure.
ABCD and A'B'C'D are congruent because A'B'C'D is the result of rotating ABCD 180 degrees about the origin.
I've included the missing graph as an attachment.
Using points A and A' as our references.
We have:
[tex]A = (-1,1)[/tex]
[tex]A' = (1,-1)[/tex]
The rule of rotation 180 degrees about the origin is:
[tex](x,y) \to (-x,-y)[/tex]
So, we have:
[tex](-1,1) \to (-(-1),-1)[/tex]
[tex](-1,1) \to (1,-1)[/tex]
The above rule is applicable to other points in ABCD and A'B'C'D'
Since the rule of transformation is rotation (a rigid transformation), then ABCD and A'B'C'D are congruent.

One angle of a parallelogram measures 63°. What are the measures of the other three angles in the parallelogram?
Answers
opposite angles of a llgrm are equal.
ABCD is a llgrm.
let angle A = 63 degree
so opposite angle of A is C is also 63.
let angle B=x degree =angle D
sum of all angles of a llgrm is 360 degree
angle A + angle B + angle C + angle D=360
63+x+63+x=360
126+2x=360
2x=360-126
x= 134/2
x=67
so the other angles are
A=63 B =67 C = 63 D = 67

Find the volume of this square
based pyramid.
10 cm
8 cm
8 cm
V = [?] cm3
Answers
Answer:
213.3
Step-by-step explanation:
The volume of a pyramid is 1/3 base times height.
Using this formula, our square base is 8*8, or 64 square units.
Multiplying that by the height, 10. We get 64*10, 640.
Finally dividing by 3, we have 213.3333333333...
Rounding that to the nearest tenth, 213.3.
The volume of the given square pyramid is 480 cubic centimeter.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Given that, Slant height of pyramid is 10 cm and base is 8 cm.
The volume of square based pyramid =a²h/3.
Now, volume = (8²×10)/3
= 213.33 cubic centimeter
Therefore, the volume of a square pyramid is 213.33 cubic centimeter.
