Geometry MCAP Review

Front

What postulate states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent?

Back

SSS (Side-Side-Side) Postulate.

Front

What happens to a figure when the scale factor is less than one?

Back

The figure undergoes a reduction.

Front

What is the correct ratio of the sides in a right triangle for cosine?

Back

Adjacent side over Hypotenuse (Adj/Hyp).

Front

Are two triangles with different side lengths similar? Why or why not?

Back

No, because similarity requires proportional corresponding sides.

Front

What is the definition of the SAS postulate?

Back

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the definition of the ASA postulate?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the definition of similar triangles?

Back

Triangles that have the same shape but may differ in size; their corresponding angles are equal and their corresponding sides are proportional.

Front

What is the relationship between the scale factor and the area of similar figures?

Back

The area of similar figures is proportional to the square of the scale factor.

Front

What is the definition of the Pythagorean theorem?

Back

In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Front

What is the formula for finding the area of a triangle?

Back

Area = 1/2 * base * height.
