Geometry Flashcard 9 (Fall Semester Review)

Front

What is the value of x, y, and m∠CED if x = 3, y = 5, and m∠CED = 13°?

Back

x = 3, y = 5, m∠CED = 13°.

Front

How do you find the missing endpoint given the midpoint (3,4) and the other endpoint (-1,6)?

Back

The missing endpoint is (7,2).

Front

What is the Law of Syllogism in logic?

Back

The Law of Syllogism states that if 'p implies q' and 'q implies r' are both true, then 'p implies r' is also true.

If soccer practice is cancelled, then you can go to the mall after school. If it is raining today, then soccer practice is cancelled. What can you conclude?

Back

If it is raining today, then you can go to the mall after school.

Front

What is the formula for finding the midpoint between two points (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the definition of a conditional statement in geometry?

Back

A conditional statement is an if-then statement that relates two propositions.

Front

What is the relationship between angles in a linear pair?

Back

Angles in a linear pair are supplementary, meaning they add up to 180°.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they are in the same plane and do not intersect.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90°.

Front

How do you calculate the distance between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).
