Final Exam 2

Front

What is the relationship between the side lengths of similar rectangles?

Back

The ratios of the corresponding side lengths of similar rectangles are equal.

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

What defines an isosceles triangle?

Back

An isosceles triangle has at least two sides that are equal in length, which also means two of its angles are equal.

Front

What is the formula to calculate the area of a rectangle?

Back

Area = length × width.

Front

If two angles are complementary, what is their sum?

Back

The sum of two complementary angles is 90 degrees.

Front

What is the measure of each interior angle in an equilateral triangle?

Back

Each interior angle in an equilateral triangle measures 60 degrees.

Front

What is the definition of perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

How do you calculate the percentage of a part relative to a whole?

Back

Percentage = (part/whole) × 100.

Front

What is the formula for the area of a triangle?

Back

Area = (base × height) / 2.

Front

What is the relationship between the angles formed when two lines intersect?

Back

When two lines intersect, the opposite angles (vertical angles) are equal, and the adjacent angles are supplementary (sum to 180 degrees).
