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

Back

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

Front

Define a parallelogram.

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

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 (a² + b² = c²).

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width (Area = length × width).

Front

Define a circle.

Back

A circle is a shape consisting of all points in a plane that are a fixed distance (radius) from a central point (center).

Front

What is the formula for the circumference of a circle?

Back

The circumference of a circle is calculated using the formula C = 2πr, where r is the radius.

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

Define similar triangles.

Back

Similar triangles are triangles that have the same shape but may differ in size; their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula Area = 1/2 × base × height.

Front

What is a transversal?

Back

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