Corresponding Parts of Congruent Triangles H

Front

What does it mean for two triangles to be congruent?

Back

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

Front

If \( \Delta ABC \cong \Delta MNO \), what can we say about the corresponding angles?

Back

The corresponding angles are equal: \( \angle A \cong \angle M \), \( \angle B \cong \angle N \), and \( \angle C \cong \angle O \).

Front

If \( AC = 34 \) in \( \Delta ABC \) and \( AC \cong MO \) in \( \Delta MNO \), what is the length of \( MO \)?

Back

The length of \( MO \) is also 34.

Front

In congruent triangles, how do you find the length of a side if you know the lengths of the corresponding sides?

Back

The lengths of corresponding sides are equal, so you can set them equal to each other and solve for the unknown.

Front

If \( \Delta DEF \cong \Delta RST \), what can we conclude about \( \angle R \)?

Back

\( \angle R \cong \angle D \).

Front

What is the relationship between corresponding sides of congruent triangles?

Back

The lengths of corresponding sides of congruent triangles are equal.

Front

If \( \Delta XYZ \cong \Delta KLM \), what is true about \( \angle Y \) and \( \angle L \)?

Back

\( \angle Y \cong \angle L \).

Front

What is the significance of sketching a picture when solving problems involving congruent triangles?

Back

Sketching a picture helps visualize the problem, making it easier to identify corresponding parts and relationships.

Front

If \( AB = 14 - x \) and \( MO = 3x - 2 \) in congruent triangles, how can you find \( x \)?

Back

Set \( AB \) equal to \( MO \) and solve for \( x \): \( 14 - x = 3x - 2 \).

Front

What does \( \angle E \cong \angle A \) imply in the context of congruent triangles?

Back

It implies that the angles are equal in measure.
