Geo- Ch. 4 Retention Review

Front

What is the probability of landing on a square or a star in a set of 16 outcomes?

Back

The probability is 10/16.

Front

What is the probability of landing on the color blue on a spinner with 12 sections, 3 of which are blue?

Back

The probability is 3/12 or 1/4.

Front

What postulate states that two triangles are similar if two angles of one triangle are equal to two angles of another triangle?

Back

AA~ (Angle-Angle Similarity Postulate).

Front

Solve the equation (4a + 3)(4a - 3) = 0.

Back

a = -3/4, 3/4.

Front

What is the zero product property in algebra?

Back

If the product of two factors is zero, at least one of the factors must be zero.

Front

Solve using the zero product property: x^2 + 2x - 24 = 0.

Back

x = -6, x = 4.

Front

What is the formula for calculating probability?

Back

Probability = (Number of favorable outcomes) / (Total number of outcomes).

Front

Define similar triangles.

Back

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

Front

What does the term 'zero product property' mean?

Back

If a * b = 0, then either a = 0 or b = 0.

Front

What is the significance of the AA~ postulate in geometry?

Back

It is used to prove that two triangles are similar based on two pairs of equal angles.
