Answer:
When a Geometrical shape is rotated through certain angle
1. Shape and size will not change, that is the two rectangles will be congruent.
2. Length of sides remain same.
3. Each angle of rectangle after rotation (image) will be equal to rectangle before rotation (Pre image).
4. Order of vertices changes.You can say it as if pre image was ABCD , then Image can be DABC or CDBA.
5. Length →breadth, and Breadth → Length.(after one rotation,either clockwise or Anticlockwise),so lengths will change.
6.Similarly sides change after a rotation,because . Length →breadth, and Breadth → Length
The properties of rectangle that will remain same are
1. Angles
2. Shape
3. Size
Answer:
Quinzel sold 17 pairs of shoes last month.
Step-by-step explanation:
Let be "Q" the number of pairs of shoes Quinzel sold last month and "J" the number of pairs of shoes Joseph sold last month.
Set up a system of equations:
Solve for "J" from the first equation:
Applying the Substitution Method, you get:
Answer:
B: y = -2x + 5
Step-by-step explanation:
-2 - 1 = -3
9 - 3 = 6
= -2
gradient = -2
3 = 1 x -2 + c
3 = -2 + c
5 = c
y intercept = 5
equation = y = -2x + 5
so the answer is option b
