Geometry Unit 5 Assessment

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 an acute angle.

Back

An acute angle is an angle that measures less than 90 degrees.

Front

What is a right angle?

Back

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

Front

Define an obtuse angle.

Back

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

Front

What is the formula for the area of a triangle?

Back

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

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that 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

Define parallel lines.

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a transversal crosses two lines.

Front

Define a polygon.

Back

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