What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.

What does CPCTC stand for in geometry?

Back

CPCTC stands for 'Corresponding Parts of Congruent Triangles are Congruent.' It is used to prove that corresponding angles and sides of congruent triangles are equal.

What is the slope of a line in the equation y = mx + b?

Back

In the equation y = mx + b, 'm' represents the slope of the line, which indicates its steepness and direction.

Front

What is the relationship between parallel lines and their slopes?

Back

Parallel lines have the same slope. If two lines are parallel, their slopes will be equal.

Front

What is the circumcenter of a triangle?

Back

The circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect. It is equidistant from all three vertices.

How do you find the measure of an angle in a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees. You can find the measure of an angle by subtracting the sum of the other two angles from 180.

Front

What is the definition of congruent triangles?

Back

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