Geometry 1st Semester Review

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in similar positions on two parallel lines cut by a transversal. They are equal in measure.

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which means all corresponding sides and angles are equal.

Front

What is the definition of collinear points?

Back

Collinear points are points that lie on the same straight line.

Front

What is the distance formula for finding the length of a line segment between two points (x1, y1) and (x2, y2)?

Back

The distance formula is: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What are Vertical Angles?

Back

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

Front

What is a transversal in geometry?

Back

A transversal is a line that intersects two or more other lines at different points.

Front

What is the definition of a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments connected end to end.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated by the formula: Area = length × width.

Front

What is the definition of complementary angles?

Back

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