Understanding Triangle Congruence

The video tutorial explains how to determine if two triangles are congruent. It introduces the concept of congruence, which means two shapes are identical in form and size. The tutorial covers the properties of triangles, including their angles and sides, and explains three rules for proving congruence: Side-Side-Side (SSS), Side-Angle-Side (SAS), and Angle-Side-Angle (ASA). Each rule is discussed in detail, highlighting the importance of knowing specific sides and angles to establish congruence between triangles.

What does it mean for two triangles to be congruent?

• They have the same angles.

• They have the same area.

• They have the same perimeter.

• They are identical in shape and size.

How many angles does a triangle have?

• Two

• Three

• Four

• Five

Which of the following is NOT a requirement for the SSS rule?

• All three sides of one triangle are equal to all three sides of another triangle.

• The angles of the triangles must be known.

• The triangles must have three sides each.

• The sides must be compared in pairs.

Which rule requires knowing all three sides of a triangle?

• ASA

• SSS

• SAS

• AAS

What does the SAS rule stand for?

• Side-Angle-Side

• Side-Side-Side

• Side-Angle-Side-Angle

• Side-Side-Angle

In the SAS rule, what must be true about the angle?

• It must be between the two sides.

• It must be an obtuse angle.

• It must be the largest angle.

• It must be the smallest angle.

What does the ASA rule stand for?

• Angle-Angle-Angle

• Angle-Angle-Side

• Angle-Side-Side

• Angle-Side-Angle

In the ASA rule, what is the position of the side?

• It is between the two angles.

• It is opposite to the largest angle.

• It is the longest side.

• It is the shortest side.

Which rule involves two angles and a side?

• SSS

• SAS

• ASA

• SSA
