Geometry Unit 5 Assessment

Front

What is the definition of a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.

Front

What is the formula for finding the perimeter of a rectangle?

Back

Perimeter = 2(length + width)

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is 180 degrees.

Front

Define complementary angles.

Back

Complementary angles are two angles whose sum is 90 degrees.

Front

What is the definition of a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What is the Pythagorean theorem?

Back

In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides (a² + b² = c²).

Front

What is the definition of a polygon?

Back

A polygon is a closed figure formed by a finite number of line segments.

Front

What is the difference between a radius and a diameter?

Back

The radius is the distance from the center of a circle to any point on its circumference, while the diameter is twice the length of the radius and passes through the center.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2(base * height)

Front

Define similar triangles.

Back

Similar triangles are triangles that have the same shape but may differ in size; their corresponding angles are equal and their corresponding sides are proportional.
