What are congruent polygons - Congruent Triangles

The video tutorial explains the concept of congruence in geometry, focusing on angles, line segments, and polygons. It begins with an introduction to congruent polygons, emphasizing the importance of congruent parts. The tutorial then delves into the congruence of angles and line segments, explaining how equal measures are represented with tick marks. Finally, it covers congruent polygons in detail, highlighting that all corresponding parts, including angles and sides, must be congruent for polygons to be considered congruent.

What does it mean for two angles to be congruent?

• They have the same measure.

• They have different measures.

• They are supplementary.

• They are complementary.

How do we represent that two angles are congruent?

• By writing their measures.

• By using tick marks.

• By using different colors.

• By drawing a circle around them.

What indicates that two line segments are congruent?

• They have the same length.

• They are parallel.

• They share the same tick mark.

• They have different tick marks.

For polygons to be congruent, what must be true?

• They must have the same number of sides.

• All corresponding angles and sides must be congruent.

• Only their sides must be congruent.

• Only their angles must be congruent.

Which of the following is NOT a requirement for congruent polygons?

• Equal angle measures.

• Equal side lengths.

• Different shapes.

• Equal number of sides.
