A right angle is an angle that measures exactly 90 degrees. In geometric terms, it is formed by two perpendicular lines that intersect, creating four 90-degree angles at the point of intersection.

- A right angle is always exactly 90 degrees.
- It is represented by the symbol ∡
- The sides of a right angle are perpendicular to each other, forming a perfect L-shape.

Some common examples of right angles include:

To understand and identify right angles, it is important to remember the following key points:

- A right angle always measures 90 degrees.
- It forms a perfect L-shape, with perpendicular sides.
- Look for examples of right angles in everyday objects and surroundings.
- Practice identifying right angles in geometric shapes and diagrams.
- Understand the symbol ∡ that represents a right angle.

Understanding right angles is essential in geometry and real-world applications. Recognizing right angles helps in measuring and constructing shapes, understanding architectural designs, and solving various mathematical problems.

Algebra: Writing, interpreting, and using mathematical expressions and equations

Students write mathematical expressions and equations that correspond to given situations, they evaluate expressions, and they use expressions and formulas to solve problems. They understand that variables represent numbers whose exact values are not yet specified, and they use variables appropriately. Students understand that expressions in different forms can be equivalent, and they can rewrite an expression to represent a quantity in a different way (e.g., to make it more compact or to feature different information). Students know that the solutions of an equation are the values of the variables that make the equation true. They solve simple one-step equations by using number sense, properties of operations, and the idea of maintaining equality on both sides of an equation. They construct and analyze tables (e.g., to show quantities that are in equivalent ratios), and they use equations to describe simple relationships (such as 3x = y) shown in a table.
