Properties of Segments and Angles

This video tutorial covers the multiplication and division properties of segments and angles in geometry. It explains that if segments or angles are congruent, their multiples or divisions are also congruent. The tutorial uses examples with points A, B, C, D, E, and F to illustrate these properties, showing how congruent segments can be multiplied or divided to maintain congruence. The multiplication property is demonstrated by doubling segment lengths, while the division property is shown by halving segment lengths.

What is the basic idea of the multiplication property in geometry?

• If segments or angles are congruent, their multiples are congruent.

• If segments or angles are congruent, they are parallel.

• If segments or angles are congruent, their divisions are congruent.

• If segments or angles are congruent, they are equal in length.

In the multiplication property example, if segment AB is 4, what is the length of segment AC?

• 10

• 6

• 4

• 8

According to the multiplication property, if AB is congruent to DE, what can be said about AC and DF?

• AC is unrelated to DF

• AC is half of DF

• AC is twice DF

• AC is congruent to DF

In the multiplication property, if AB is 4 and DE is 4, what is the length of DF?

• 6

• 10

• 8

• 4

What is the result of multiplying congruent segments by the same factor?

• The segments become parallel.

• The segments become unrelated.

• The segments become perpendicular.

• The segments remain congruent.

What is the division property of segments and angles?

• If segments or angles are congruent, their divisions are congruent.

• If segments or angles are congruent, they are parallel.

• If segments or angles are congruent, their multiples are congruent.

• If segments or angles are congruent, they are equal in length.

In the division property example, if AC is 12, what is the length of segment AB?

• 6

• 12

• 9

• 3

If AC is congruent to DF and AC is 12, what is the length of DE if E is the midpoint of DF?

• 3

• 12

• 6

• 9

What happens to the segments when you apply the division property?

• They become unrelated.

• They remain the same length.

• They become twice as long.

• They become half as long.

In the division property, if AC is 12 and AB is 6, what is the length of BC?

• 3

• 12

• 6

• 9
