Geometry Chapter 1-3 Assessment

Front

What is the definition of complementary angles?

Back

Two angles whose measures add up to 90 degrees.

Front

What is the distance formula in geometry?

Back

The distance between two points (x1, y1) and (x2, y2) is given by: d = √((x2 - x1)² + (y2 - y1)²).

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines it intersects.

Front

What is the definition of vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

If DF = 9x - 39, what is EF when x = 5?

Back

EF = 58.

Front

What is the reflexive property of congruence?

Back

Any geometric figure is congruent to itself.

Front

What is the substitution property?

Back

If two quantities are equal, one can be substituted for the other in any expression.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

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 is the definition of corresponding angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal.
