Semester 1 exam review

Front

What is the definition of similar triangles?

Back

Similar triangles are triangles that have the same shape but may differ in size. Their corresponding angles are equal, and the lengths of their corresponding sides are proportional.

Front

What does SAS stand for in triangle similarity?

Back

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

Front

How do you find the missing side length in similar triangles?

Back

To find the missing side length in similar triangles, set up a proportion using the lengths of the corresponding sides of the triangles and solve for the unknown.

Front

What is the formula for probability?

Back

The formula for probability is P(E) = Number of favorable outcomes / Total number of outcomes.

Front

What is the probability that Federer won the point when his first serve was in if the probability is 0.674?

Back

The probability that Federer won the point when his first serve was in is 0.674.

Front

How do you solve a two-step equation?

Back

To solve a two-step equation, first isolate the variable term by performing the inverse operation on the constant term, then solve for the variable.

Front

Back

The solution to the equation is x = 2.

Front

What is the definition of the SSS criterion for triangle similarity?

Back

SSS stands for Side-Side-Side. It is a criterion for triangle similarity that states if the lengths of all three sides of one triangle are proportional to the lengths of the corresponding sides of another triangle, then the triangles are similar.

Front

What is the relationship between the angles of similar triangles?

Back

In similar triangles, the corresponding angles are equal.

Front

How do you determine if two triangles are similar using the AA criterion?

Back

Two triangles are similar if two angles of one triangle are equal to two angles of another triangle.
