Answer:
Answer: Sample Response: The height of the triangle will be twice the height of the rectangle. The area of a triangle is ½ bh and the area of a rectangle is bh. If the bases are the same, then the height of the triangle has to be double that of the rectangle in order to get the same area.
Step-by-step explanation:
Naming the circle is just the only point in the center of the circle (E). The radius is half diameter of the circle so imagine a line connecting the center dot to any dot to the outside. An example of this would be (EC). The diameter is half the circle so any 3 points that cut the circle in half. This could be either (DEC) or (AEB).
So the answers would be:
A: (E)
B: (EC)
C: (DEC)
D: (AEB)
Answer:
J (-4 , 1) -> J' (1 , 4)
K (-2 , 1) -> K' (1 , 2)
L (-2 , 5) -> L' (5 , 2)
Step-by-step explanation:
clockwise rotation 90°: (x,y) -> (y,-x)
J (-4 , 1) -> J' (1 , 4)
K (-2 , 1) -> K' (1 , 2)
L (-2 , 5) -> L' (5 , 2)
