MMA Summative Review 2.7

Front

What are orthogonal lines?

Back

Lines that are at right angles (90 degrees) to each other, often used in perspective drawing to create depth.

Front

Define perspective in mathematics.

Back

A mathematical system used to represent three-dimensional objects on a two-dimensional surface, showing depth and the observer's location.

Front

What is a horizon line?

Back

A horizontal line that represents the viewer's eye level in perspective drawing.

Front

What are vertical lines?

Back

Lines that run up and down, perpendicular to the horizon line, used to depict height in perspective.

Front

What is the formula to find the height a ladder reaches against a wall?

Back

Using the Pythagorean theorem: height = √(length² - distance from wall²).

Front

If a ladder is 12 feet long and placed 4 feet from the wall, how high does it reach?

Back

11.3 feet.

Front

What are horizontal lines?

Back

Lines that run left to right, parallel to the horizon line, used to depict width in perspective.

Front

Explain the concept of similarity in geometry.

Back

Similarity refers to figures that have the same shape but may differ in size, maintaining proportional dimensions.

Front

What is symmetry in geometry?

Back

A property where a shape or object is identical on both sides of a dividing line or around a central point.

Front

How do you identify orthogonal lines in a perspective drawing?

Back

Look for lines that converge towards a vanishing point, indicating depth.
