Geometry and Algebra Practice

A series of flashcards covering key terms and concepts related to geometry and algebra as discussed in the lecture notes.

Hypotenuse

The longest side of a right triangle, opposite the right angle.

Legs of a triangle

The two shorter sides of a right triangle that form the right angle.

Area of a rectangle

Calculated by the formula A = l × w, where l is the length and w is the width.

Square root

A value that, when multiplied by itself, gives the original number; denoted as √x.

Pythagorean theorem

A formula used to determine the relationship between the sides of a right triangle: a² + b² = c².

Volume of a rectangular prism

Calculated as V = l × w × h, where l is the length, w is the width, and h is the height.

Percent

A fraction expressed as a part of 100; represented with the symbol %.

25% of 100

Equals 25; a quarter of a whole.

Area of a square

Calculated using the formula A = s², where s is the length of a side.
