What else can I help you with?
What is a figure that can be rotated less than 360 degrees about its center and still look exactly the same exactly the same as the originial?
A circle
How many lines of symmetry does a a circle have and how do you know?
A circle has infinite lines of symmetry caused by its diameter which can be rotated inside the circle.
What is rotated 360 degrees on its axis is called a dome?
A quarter circle
Is there an object that can be translated so that it's end result is exactly the same as the original object?
A circle/sphere, a square/cube
Can a circle be changed into a sphere?
No. A circle is a 2-dimensional object a sphere is 3-d. However, a circle would generate a sphere if rotated about a diameter.
What shape will stay the same no matter how many degrees it is rotated?
a square,circle,pentagon
What is the shape of half moon?
it is similar to a half circle but it the half circle is connected from end to end and it is rotated 90 degrees to the left and or right
What degrees can you rotate a shape at?
A shape can usually be rotated through a full circle of 360 degrees.
A tangent line is a line that intersects a circle at exactly two points?
No. A tangent touches the circle at exactly one point. A line that intersects a circle at exactly two points is a secant.
Which statement follows logically from the statement If a line is tangent to a circle then it intersects the circle at exactly one point?
If a line intersects a circle at exactly one point, it is a tangent to that circle
The radius of a circle is multiplied by 4 Its area is how many times bigger than the original circle?
Area of the original circle = πr2 Area of enlarged circle = π(4r)2 = π16r2 The enlarged circle is 16 time as big as the original circle.
Are line may intersect a circle at exactly one point?
A tangent line touches the circumference of a circle exactly at one point.
