Symmetry and Geometry Concepts

Front

What is symmetry in geometry?

Back

Symmetry in geometry refers to a balance or correspondence between two halves of a shape, where one half is a mirror image of the other.

Front

Define line symmetry.

Back

Line symmetry occurs when a shape can be divided into two identical halves that are mirror images of each other along a line.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a central point and still look the same at certain angles.

Front

Explain point symmetry.

Back

Point symmetry exists when every part of a shape has a matching part at an equal distance from a central point, but in the opposite direction.

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, including translations, rotations, reflections, and dilations.

Front

What is a translation?

Back

A translation is a type of transformation that slides a shape from one position to another without rotating or flipping it.

Front

Define rotation in geometry.

Back

Rotation is a transformation that turns a shape around a fixed point at a certain angle.

Front

What is reflection in geometry?

Back

Reflection is a transformation that flips a shape over a line, creating a mirror image.

Front

What does dilation mean in geometry?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same.

Front

What is the SAS Congruence Theorem?

Back

The SAS Congruence Theorem states that if two sides of one triangle are equal to two sides of another triangle, and the included angles are equal, then the triangles are congruent.
