each is a right angle
A right angle is a type of angle that measures exactly 90 degrees
A right angle is a type of angle that measures exactly 90 degrees. It is formed when two lines or line segments intersect each other perpendicularly, meaning they meet at a right angle.
When two lines or line segments form a right angle, the sides of the angle are perpendicular to each other. This means that they meet or intersect at a 90-degree angle, creating four equal 90-degree angles in total.
For example, if you draw a square, all four corners of the square will have right angles. Each corner of the square forms a 90-degree angle, making the square a shape with four right angles.
In addition to squares, there are various other examples of shapes that contain right angles, such as rectangles, parallelograms, and even triangles (if they are right triangles).
To determine if an angle is a right angle, you can use a protractor to measure its angle or simply visually assess whether the angle appears to be formed at 90 degrees.
Remember, a right angle is a specific type of angle with a measurement of 90 degrees, formed when two lines or line segments intersect perpendicularly.
