Front

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

What does it mean for two shapes to be congruent?

Back

Two shapes are congruent if they have the same size and shape, meaning one can be transformed into the other through rigid motions (translations, rotations, reflections).

Front

What are rigid motions in geometry?

Back

Rigid motions are transformations that preserve distance and angle measures, including translations, rotations, and reflections.

Front

What is the Side-Side-Side (SSS) congruence criterion?

Back

The SSS congruence criterion states that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

How do you determine the perimeter of a triangle?

Back

The perimeter of a triangle is found by adding the lengths of all three sides.

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 significance of midpoints in geometry?

Back

Midpoints are points that divide a segment into two equal parts, often used in constructions and proofs.

Front

What is a regular polygon?

Back

A regular polygon is a polygon with all sides and angles equal.

Front

What is the formula for the perimeter of a polygon?

Back

The perimeter of a polygon is the sum of the lengths of all its sides.

Front

What is the relationship between transformations and congruence?

Back

Transformations such as translations, rotations, and reflections can show that two figures are congruent if one can be mapped onto the other.
