Front

Find the image of the point (3, 2) that has undergone a reflection across the x-axis.

Back

(3, -2)

Front

Which term describes this figure? (Choose from: Angle, Ray, Line segment, Line)

Back

Ray

Front

Which is a rule for a reflection over the x-axis? (Choose from: f(x,y)=(x,-y), f(x,y)=(-x,y), f(x,y)=(-y,x), f(x,y)=(y,-x))

Back

f(x,y)=(x,-y)

Front

The CIRCUMCENTER is the intersection of which special segments? (Choose from: Angle Bisectors, Perpendicular Bisectors, Medians, Altitudes)

Back

Perpendicular Bisectors

Front

Define a tessellation.

Back

A tessellation is a pattern of shapes that fit perfectly together without any gaps or overlaps.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the difference between a ray and a line segment?

Back

A ray has one endpoint and extends infinitely in one direction, while a line segment has two endpoints and is finite.

Front

What is the definition of a circumcenter?

Back

The circumcenter is the point where the perpendicular bisectors of a triangle intersect, and it is equidistant from the triangle's vertices.

Front

What is the formula for finding the image of a point (x, y) after a reflection over the y-axis?

Back

(x, -y)
