Front

What is the definition of a point in geometry?

Back

A point is a specific location in space that has no dimensions, represented by a dot.

Front

What is a line segment?

Back

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

Front

Define a ray in geometry.

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

Front

What is the difference between parallel and perpendicular lines?

Back

Parallel lines never intersect and are always the same distance apart, while perpendicular lines intersect at a right angle (90 degrees).

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

How do you calculate the perimeter of a triangle?

Back

Perimeter = side1 + side2 + side3.

Front

What is a polygon?

Back

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

Front

Define a circle in geometry.

Back

A circle is a set of points in a plane that are equidistant from a fixed point called the center.

Front

What is the Pythagorean Theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

What are complementary angles?

Back

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