What is the SSS and SAS Congruence Theorems - Congruent Triangles

The video tutorial covers the concepts of SSS (side-side-side) and SAS (side-angle-side) congruence in triangles. It explains that congruent triangles have equal angles and sides. The SSS congruence criterion is discussed, where all three sides of one triangle are equal to the corresponding sides of another triangle. The SAS criterion is also explained, where two sides and the included angle of one triangle are equal to the corresponding parts of another triangle. The tutorial emphasizes the importance of these criteria in proving triangle congruence.

What does it mean for two angles to be congruent?

• They are adjacent angles.

• They are part of the same triangle.

• They have the same measure.

• They have different measures.

In the SSS congruence criterion, what do the tick marks on the sides of a triangle represent?

• Triangles are isosceles.

• Triangles are similar.

• Sides are equal.

• Angles are equal.

If two triangles are congruent by SSS, what can be said about their angles?

• The angles are complementary.

• The angles are not necessarily equal.

• The angles are equal in measure.

• Only one angle is equal.

In the SAS congruence criterion, where must the angle be located?

• At the base of the triangle.

• Outside the triangle.

• Between the two sides.

• At the end of the triangle.

What does the SAS criterion tell us about the remaining sides and angles of the triangles?

• Only the angles are equal.

• Only the sides are equal.

• They are equal.

• They are not equal.
