Geometry Semester 1

Front

What is the CENTROID of a triangle?

Back

The centroid is the point where the three medians of a triangle intersect.

Front

What are the special segments that intersect at the centroid?

Back

Medians.

Front

Define an altitude in a triangle.

Back

An altitude is a line segment that runs from a vertex of a triangle to the opposite side, intersecting it at a 90-degree angle.

Front

What is a line segment?

Back

A line segment is part of a line that has two endpoints.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect.

Front

What is a median in a triangle?

Back

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

Front

What is the difference between complementary and supplementary angles?

Back

Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

What are alternate interior angles?

Back

Alternate interior angles are angles that lie between two parallel lines on opposite sides of a transversal.
