What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to produce a new shape. Common transformations include translation, rotation, reflection, and dilation.

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which means their corresponding sides and angles are equal.

Front

What is the result of rotating a shape 90° clockwise about the origin?

Back

When a shape is rotated 90° clockwise about the origin, each point of the shape moves to a new position that is 90° around the origin in a clockwise direction.

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart and have the same slope.

Front

What is the definition of perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image of the original shape.

Front

What is the relationship between the diagonals of a square?

Back

The diagonals of a square are congruent (equal in length) and perpendicular (intersect at a right angle).

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is the definition of a rotation in geometry?

Back

A rotation is a transformation that turns a shape around a fixed point, known as the center of rotation, by a certain angle.

Front

What is the difference between a translation and a reflection?

Back

A translation moves a shape from one location to another without changing its orientation, while a reflection flips the shape over a line, creating a mirror image.
