Geometry Chapter 7 Unit Assessment Review - 3rd Period

Front

What is the formula for finding the length of a shadow based on similar triangles?

Back

The length of the shadow can be found using the proportion: (Height of object 1 / Length of shadow 1) = (Height of object 2 / Length of shadow 2).

Front

Define similar triangles.

Back

Triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What does SSS∼ stand for in triangle similarity?

Back

SSS∼ stands for 'Side-Side-Side similarity', which means that if the three sides of one triangle are proportional to the three sides of another triangle, then the triangles are similar.

Front

What does AA∼ stand for in triangle similarity?

Back

AA∼ stands for 'Angle-Angle similarity', which means that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is the significance of the statement in a geometric proof?

Back

The statement in a geometric proof provides a specific assertion that is being demonstrated or established as true.

Front

How do you solve for x in an equation?

Back

To solve for x, isolate x on one side of the equation using inverse operations.

Front

What is the height of a statue if it casts a shadow of 253.1 ft and a man casts a shadow of 36.6 ft?

Back

The height of the statue is 42.9 ft.

Front

If two triangles have one angle equal and the sides including that angle are proportional, what can be concluded?

Back

The triangles are similar by the SAS∼ (Side-Angle-Side similarity) criterion.

Front

What is the relationship between the angles in similar triangles?

Back

In similar triangles, corresponding angles are equal.

Front

What is the first step in solving a proportion?

Back

Cross-multiply the terms to create an equation.
