Front

What is the difference between parallel and perpendicular lines?

Back

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

Define a polygon.

Back

A polygon is a closed figure formed by a finite number of straight line segments that connect to form a closed chain.

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

Explain 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 (a² + b² = c²).

Front

What is a transversal line?

Back

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

Front

Define congruent figures.

Back

Congruent figures are figures that have the same shape and size, but may be oriented differently.
