What is a rhombus?

Back

A rhombus is a quadrilateral with all sides equal in length, but angles are not necessarily 90 degrees. Its diagonals bisect each other at right angles but are not necessarily congruent.

Front

What does CPCTC stand for?

Back

CPCTC stands for 'Corresponding Parts of Congruent Triangles are Congruent.' It is used in proofs to show that corresponding parts of triangles are equal.

What is the Vertical Angle Theorem?

Back

The Vertical Angle Theorem states that when two lines intersect, the opposite (or vertical) angles are equal.

Front

How do you find the area of a rectangle?

Back

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

Front

What is the Pythagorean Theorem?

Back

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): a² + b² = c².

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 is a parallelogram?

Back

A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. Opposite angles are also equal.
