CC3 Chapter 9 Review

Front

What is an alternate interior angle?

Back

An alternate interior angle is formed when a transversal crosses two parallel lines. The angles are on opposite sides of the transversal and inside the two lines.

Front

Identify the properties of a right triangle.

Back

A right triangle has one angle that measures 90 degrees. The side opposite the right angle is the hypotenuse, and the other two sides are called the legs.

Front

How do you calculate the length of a walkway using the Pythagorean theorem?

Back

To find the length of a walkway, use the formula a² + b² = c², where c is the hypotenuse (length of the walkway), and a and b are the lengths of the other two sides.

Front

What is the relationship between same side interior angles?

Back

Same side interior angles are formed when a transversal crosses two parallel lines. They are on the same side of the transversal and inside the two lines, and they are supplementary (add up to 180 degrees).

Front

How do you find the height of a roof using a right triangle?

Back

To find the height of a roof, use the formula for the area of a triangle (Area = 1/2 * base * height) or apply trigonometric ratios if angles are known.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points, creating various angles.

Front

What are corresponding angles?

Back

Corresponding angles are formed when a transversal crosses two parallel lines. They are in the same position at each intersection and are equal in measure.

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

How do you determine if two lines are parallel using angle relationships?

Back

If a transversal creates alternate interior angles that are equal, or same side interior angles that are supplementary, then the lines are parallel.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 * base * height.
