Study Notes

Quadrilaterals

A parallelogram is a type of quadrilateral with opposite sides parallel and congruent.

Area of a Circle

The formula for finding the area of a circle is A = πr², where r represents the radius.

Interior Angles of a Regular Pentagon

The measure of each interior angle in a regular pentagon is 108 degrees.

Transformations in Geometry

Common types of transformations include translation, rotation, reflection, and dilation. An option that does not correspond to a transformation may include an unrelated geometric property.

Pythagorean Theorem

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). This is expressed as c² = a² + b².
