Triangle Line Segments - a start

Front

What defines congruent triangles?

Back

Congruent triangles have the same shape and size.

Front

What is the transformation from triangle ABC to triangle A'B'C'?

Back

The transformation is a reflection across the x-axis.

Front

What is a median in a triangle?

Back

A median is a line segment that connects a vertex to the midpoint of the opposite side.

Front

What is an angle bisector?

Back

An angle bisector is a line segment that divides an angle into two equal angles.

Front

What is the triangle inequality theorem?

Back

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

What are the properties of isosceles triangles?

Back

In an isosceles triangle, two sides are of equal length, and the angles opposite those sides are also equal.

Front

What is the difference between a median and an altitude in a triangle?

Back

A median connects a vertex to the midpoint of the opposite side, while an altitude is a perpendicular segment from a vertex to the line containing the opposite side.

Front

What is the significance of the centroid in a triangle?

Back

The centroid is the point where the three medians of a triangle intersect, and it is the center of mass.

Front

What is a right triangle?

Back

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

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
