Day 79: 6.MG.4 Congruent Figures

Front

What is line symmetry?

Back

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

Front

How do you determine the number of lines of symmetry in a shape?

Back

To determine the number of lines of symmetry, you can draw lines through the shape and see how many ways you can fold it so that both halves match perfectly.

Front

What is a congruent figure?

Back

Congruent figures are shapes that are the same size and shape, meaning they can be superimposed on each other.

Front

If a shape has 2 lines of symmetry, what does that mean?

Back

It means that you can draw two different lines through the shape such that each side is a mirror image of the other.

Front

How many lines of symmetry does a square have?

Back

A square has 4 lines of symmetry.

Front

What is the line of symmetry for a rectangle?

Back

A rectangle has 2 lines of symmetry: one vertical and one horizontal.

Front

How many lines of symmetry does a circle have?

Back

A circle has an infinite number of lines of symmetry.

Front

What is the relationship between congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

If ∠A ≅ ∠M, what does this mean?

Back

It means that angle A is congruent to angle M, indicating they have the same angle measurement.

Front

What is a regular polygon?

Back

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