Corresponding Sides and Angles

Front

What are corresponding sides in triangles?

Back

Corresponding sides are sides in two triangles that are in the same relative position. For example, if triangle ABC is similar to triangle DEF, then side AB corresponds to side DE.

Front

What are corresponding angles in triangles?

Back

Corresponding angles are angles in two triangles that are in the same relative position. For example, if triangle ABC is similar to triangle DEF, then angle A corresponds to angle D.

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

If triangle ABC is similar to triangle DEF, what can we say about their angles?

Back

Angle A = Angle D, Angle B = Angle E, Angle C = Angle F.

Front

If AB = 4 cm and DE = 8 cm, what is the ratio of the corresponding sides?

Back

The ratio of the corresponding sides is 1:2.

Front

What is the relationship between corresponding sides of similar triangles?

Back

The lengths of corresponding sides of similar triangles are proportional.

Front

If angle A corresponds to angle E, what can we say about their measures?

Back

The measure of angle A is equal to the measure of angle E.

Front

What is the significance of congruent segments in triangles?

Back

Congruent segments in triangles indicate that the sides are equal in length, which is important for establishing similarity or congruence.

Front

How do you determine which angle corresponds to a given angle in a triangle?

Back

To determine the corresponding angle, look for the angle that is in the same position relative to the other angles in the similar triangle.

Front

What is the definition of congruence in geometry?

Back

Congruence means that two figures have the same shape and size, which can be shown by superimposing one figure over the other.
