If a right circular cone is intersected by a plane only at its vertex what shape is produced
The intersection will consist of only one point.
Reflectional symmetry is the quality a design has if it maintains all characteristics when it is rotated about a point of symmetry
A line has rotational symmetry
A point of symmetry divides a design so that every point on one side coincides with a point on the other side
A point of symmetry is a point around which a shape can be rotated without changing any of its characteristics
If it says rotated it's true
If it says reflected it is false
You can bisect an angle using the paper folding technique
Yes, you can bisect an angle using the paper folding
technique.
Which of the following are the tools which allowed the Greeks to exploit the five basic postulates of Euclidian geometry
One can find an angle bisector using a compass and a straightedge construction or a straightedge and tracing paper construction
To find the midpoint of a segment fold the paper so that the two endpoints of the sement match up
If you fold the line segment in half so that the two ends are
touching and then crease the paper, the crease will go right
through the midpoint of the line segment.
For every point on one side of a line of symmetry there is a corresponding point on the other side of the line symmetry
When a line of symmetry divides an image its spells the image into two congruent parts on either side of the line symmetry
Is it true that a shape with rotational symmetry can be rotated around a point so that all of its characteristics are maintained
It only has rotional symmetry if it can be rotated around a
point less than 360 degrees and staying the same shape like if you
rotate a square 90 degrees it will be the same shape as in the
beginning.. Kind of confusing
What symmetry is the quality a design has if it maintains all characteristics when it is rotated about an axis lying in its plane
Does the parallel postulate in Euclidean geometry work in spherical geometry
What does not describe a rigid motion transformation
Which of the following describes a rigid motion transformation A enlarging a photo B spinning a spinner C filling a tire with air D slicing a log into sections
Which transformations will result in an image that maps onto itself
What is the number of sides a polygon can have to form a regular tessellation
It can have 3, 4 or 6 sides.
If a right circular cone is intersected by a plane only at its vertex as in the picture below what shape is produced
The answer will depend on the angle formed between the plane and
the axis of the cone. Since there is no picture "below" it is not
possible to determine that and therefore it is impossible to give
an answer.
