When ABC is reflected across x 1 and y -3. What are the coordinates of the reflection image of A after both reflections?
The answer will depend on the original coordinates of A: these have not been provided so neither has an answer.
What is the relationship between vertical angles?
Vertical angles have the same angle measure. Vertical angles are formed by two intersecting lines that look like an "x". Angles that are across from each other on this "x" are called vertical angles.
Which transformations can be used to carry the rectangle ABCD onto itself?
There are the identity transformations:translation by (0, 0)enlargement by a scale factor of 0 - with any point as centre of enlargement.In addition, it can be reflection about the perpendicular bisector of any side of the rectangle, or a rotation of 180 degrees about the centre of the rectangle.
A composition of reflections across two intersecting lines is a?
Rotation
Is glide reflection equivalent to two reflections across two vertical lines?
No. Glide reflection is a combination of an ordinary reflection and a slide along the line of reflection. A two reflections across two vertical lines is a translation without any reflection or rotation.
What do reflections occur across?
They occur across an axis of symmetry.
What does the mathematical word intersecting mean?
"cutting across"
A composition of reflections across two parallel lines is a?
translation
What are properties of reflections m?
Reflections in mathematics preserve the size and shape of the object being reflected. They also have the property that the reflected image is the same distance from the line of reflection as the original object. Additionally, reflections can be described by an axis of reflection, which serves as a line that the reflection occurs across.
What does reversed mean in reflections?
In reflections, "reversed" means that the image appears flipped from left to right compared to the original object. Each point on the object is reflected across the mirror line to create the reversed image.
How do you construct adjacent congruent angles?
Draw to lines intersecting each other. The angles across from each other will be both congruent and adjacent
How can you tell from the coordinates that two points are reflections of each other across the y axis?
The coordinates will be the same numerically but with different + and - signs.
A figure in the coordinate plane is reflected across the line y=x+2 and then across the line y=x+4. what is the translation vector that describes the composition of the reflections Give your answer in vector format?

What are examples of glide reflections?
Examples of glide reflections include sliding a shape along a line while also reflecting it across that line. For instance, sliding and reflecting a triangle across a mirror line simultaneously creates a glide reflection. Another example could involve sliding and reflecting a letter along a surface, resulting in a glide reflection transformation.
What is the meaning intersect?
To cross paths; to be across something (basically). Intersecting lines in simple geometry are lines that lie across each other and divide one line into 360 degrees. For more detail, look it up on Webster online or something.
