Rotations&Translations&Reflection
| Question | Answer |
|---|---|
| What is a rotation? | A transformation around a point/center that moves the original point a certain point to create a rotated point. |
| What the rule for rotating a figure 90 degrees? | (x,y) --> (-y,x) |
| (x,y) --> (-x,-y) What degree did i rotate by? | 180 degrees |
| Whats another word for isometry? | Reflection |
| How do you reflect a figure across the x-axis? | (x,y) ----> (x,-y) |
| Whats the rule for reflection across the y=x ? | (x.y)---> (y,x) |
| What is a point? | Named a location and has no size. |
| How do you label a line? | lowercase cursive letter or two points on a line |
| What is a vertex? | Intersection of 2 or more lines, segments or rays. |
| How do you label a plane? | 3 points on the plane or capital cusive letter. |
| What is a segment? | A part of a line containing 2 points and all points inbetween. |
| How can you locate an endpoint? | Just look for a capital letter. |
| What is a ray? | Starts an an endpoint and extends forever in one direction |
| Whats the difference between a ray and an opposite ray? | A ray is one line that extends forever, while an opposite ray is two rays that have a common endpoint. |
| What does collinear mean? | Points that lie on the same line. |
| What does coplanar mean? | Points that lie on the same plane. |
| How do you reflect a shape across the y-axis? | (x,y) --> (-x,y) |
| How do you translate an image? | Along a vector. |
| Whats the rule for translating along a vector? | (x,y) ---> (x+a,y+b) |
| What is a line? | A straight path with no thickness and extends forever. |
| What is line symmetry? | When a figure can be reflected across a line so the images match up |
| What is line of symmetry? | Divides the figure into two congruent halves. |
| What is rotational symmetry? | If a figure can be rotated around a point by an angle betwwen zero and 360 degrees |
| What is plane symmetry? | A 3-D figure can be cut by a plane and will create two equal figures. |
| What is symmetry about an axis? | If a 3-D figure can be rotated around a line and the shape doesn't change. |
