How to use AAA to determine if two triangles are similar

The video tutorial discusses how to determine if two triangles are similar. It introduces the problem and reviews three methods to prove similarity: angle-angle, side-angle-side, and side-side-side. The tutorial then applies the angle-angle method to demonstrate that two given triangles are similar by calculating their angles. The conclusion confirms the similarity and provides a similarity statement.

What is the task given in the problem regarding the triangles?

• Find the perimeter of the triangles.

• Determine if the triangles are similar and write a similarity statement.

• Calculate the area of the triangles.

• Determine if the triangles are congruent.

Which method is used to prove similarity if two angles of one triangle are equal to two angles of another triangle?

• Side-Side-Side (SSS)

• Side-Angle-Side (SAS)

• Angle-Angle (AA)

• Angle-Side-Angle (ASA)

What is the third method to prove triangle similarity besides Angle-Angle and Side-Angle-Side?

• Angle-Angle-Angle (AAA)

• Side-Side-Side (SSS)

• Side-Angle-Angle (SAA)

• Angle-Side-Angle (ASA)

How do you find the missing angle in a triangle if two angles are known?

• Add the two known angles and subtract from 360 degrees.

• Multiply the two known angles.

• Add the two known angles and subtract from 180 degrees.

• Divide the sum of the two known angles by 2.

What is the similarity statement for the triangles discussed in the lesson?

• Triangle SMK is congruent to triangle RQT.

• Triangle SMK is different from triangle RQT.

• Triangle SMK is similar to triangle RQT.

• Triangle SMK is identical to triangle RQT.
