Fall Semester Exam Review

Front

What is the distance formula used to find the length between two points A(x1, y1) and B(x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is the definition of a scalene triangle?

Back

A scalene triangle is a triangle in which all three sides are of different lengths.

Front

What does it mean for two lines to be intersecting?

Back

Intersecting lines are lines that cross each other at one point.

Front

What is the Angle Bisector Theorem?

Back

The Angle Bisector Theorem states that the angle bisector divides the opposite side into segments that are proportional to the adjacent sides.

Front

What is the Isosceles Triangle Theorem?

Back

The Isosceles Triangle Theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are also congruent.

Front

What is the Third Angles Theorem?

Back

The Third Angles Theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect; they are always congruent.

Front

What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.
