What is the value of x for the given trapezoid?
x = 30
In circle D, m∠CFE is 49 degrees. Find the m∠CDE.
outside arc = 2*inscribed = 98 degrees
Using the figure, what is the measure of ∠ABC?
2(32)+20 = 84 degrees
Identify the location of A' after triangle ABC has been rotated 270° clockwise.
(-5,2)
Figure ABCD is reflected across the x-axis and then reflected across the y -axis to create ΔA'B'C'D'. What is the location of A'?
(6, -6)
The vertices of Quadrilateral ABCD have integral coordinates. Quadrilateral ABCD will be reflected across the line y = x and then translated 3 units to the right. What are the coordinates of the vertex B' on the transformed figure?
(10, -4)
Dilate Quadrilateral ABCD about the origin using a scale factor of 1/2. What is the location of A'?
(-6 *0.5, 6*0.5) = (-3, 3)
Is the transformation occuring A) Rotation 90 degrees counterclockwise; B) Reflection across y=x; C) Reflection across y=-x; D)Rotation 180 degrees clockwise?
B) Reflection across y = x
The vertices of the polygon shown have integral coordinates. The polygon will be dilated by a factor of 2 about the fixed point C (4, 6). What will the coordinates of R' be after the dilation is completed?
(2, -4)
