What does AA stand for in triangle similarity?

Back

AA stands for Angle-Angle similarity criterion, which states that if two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

Front

What does SAS stand for in triangle similarity?

Back

SAS stands for Side-Angle-Side similarity criterion, which states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, the triangles are similar.

Front

What does SSS stand for in triangle similarity?

Back

SSS stands for Side-Side-Side similarity criterion, which states that if the three sides of one triangle are proportional to the three sides of another triangle, the triangles are similar.

Front

How do you determine if two triangles are similar?

Back

You can determine if two triangles are similar by using one of the similarity criteria: AA, SAS, or SSS.

Front

What is the angle of depression?

Back

The angle of depression is the angle formed by a horizontal line and the line of sight to an object below the horizontal line.

Front

If a kite is 30 meters long and the angle of depression to the person holding it is 65 degrees, how do you find the height of the kite?

Back

Use the sine function: height = string length * sin(angle of depression). In this case, height = 30 * sin(65°) = 28 meters.

Front

What is the formula for finding the height of an object using trigonometry?

Back

Height = distance from the object * tan(angle of elevation) or height = string length * sin(angle of depression).

Front

If two triangles are similar, what can be said about their corresponding sides?

Back

The corresponding sides of similar triangles are in proportion.

Front

What is the relationship between the angles of similar triangles?

Back

The corresponding angles of similar triangles are equal.

Front

How do you find missing lengths in similar triangles?

Back

Set up a proportion using the lengths of the corresponding sides of the similar triangles and solve for the missing length.
