Congruent Triangles and Transformations

The video tutorial covers lesson 8 practice, focusing on triangle congruence and transformations. It explains how to determine congruence using transformations like reflection, rotation, and translation. The tutorial also provides instructions for mapping transformations and gives homework guidance.

What does it mean when two triangles are congruent?

• They have the same area.

• They have the same shape and size.

• They have the same perimeter.

• They have the same angles but different side lengths.

Which transformation involves flipping a figure over a line?

• Translation

• Rotation

• Dilation

• Reflection

After reflecting a triangle over the y-axis, what additional transformation is needed to map it onto another triangle?

• Rotation

• Translation

• Scaling

• Dilation

Which statement is NOT true about congruent triangles?

• Corresponding angles are equal.

• Corresponding sides are equal.

• The triangles have different shapes.

• The triangles have the same size.

What sequence of transformations can prove two figures are congruent?

• Dilation followed by rotation

• Translation followed by scaling

• Rotation followed by translation

• Reflection followed by dilation

Why might two figures not be congruent even after a reflection?

• They have different sizes.

• They have different positions.

• They have different colors.

• They have different orientations.

Which part of triangle ABC corresponds to part of triangle FED?

• Side BC corresponds to side FE

• Side AB corresponds to side DE

• Angle B corresponds to angle D

• Angle A corresponds to angle F

What is the first step in mapping triangle ABC to triangle FED using transformations?

• Rotate triangle ABC

• Dilate triangle ABC

• Translate triangle ABC

• Reflect triangle ABC

What is the final step in mapping triangle ABC to triangle FED?

• Translate triangle ABC

• Rotate triangle ABC

• Reflect triangle ABC

• Dilate triangle ABC
