IM Geometry: Unit 2 Lesson 3 Practice Problems

Front

What is a ray in geometry?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size, meaning all corresponding sides and angles are equal.

Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a figure into two mirror-image halves.

Front

How do you determine corresponding sides in congruent figures?

Back

Corresponding sides in congruent figures are the sides that are in the same relative position in each figure.

Front

What is the significance of the order of labeling in congruence statements?

Back

The order of labeling is significant because it indicates which parts of the figures correspond to each other.

Front

What is the definition of parallel lines?

Back

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

Front

What is the relationship between angles formed by parallel lines and a transversal?

Back

When a transversal crosses parallel lines, it creates corresponding angles that are equal and alternate interior angles that are also equal.

Front

What is a congruence statement?

Back

A congruence statement is a mathematical statement that indicates two figures are congruent, typically written in the form 'Figure A ≅ Figure B'.

Front

What does it mean for points to be equidistant from a line?

Back

Points are equidistant from a line if they are the same distance away from the line, which can indicate symmetry.

Front

How can you verify if two angles are congruent?

Back

Two angles can be verified as congruent by measuring them and checking if their measures are equal.
