Geometry A Final Exam

Front

Solve for x: 2x + 3 = -5

Back

x = -4

Front

What does SSS stand for in triangle congruence?

Back

Side-Side-Side: If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is the definition of a linear pair?

Back

A linear pair consists of two adjacent angles whose non-common sides form a straight line.

Front

Does a triangle with these side lengths exist? 7, 10, 5

Back

Yes, it satisfies the triangle inequality theorem.

Front

What is the Triangle Inequality Theorem?

Back

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

Solve for the missing angle: m∠A + m∠B = 180, m∠A = 70

Back

m∠B = 110

Front

What does SAS stand for in triangle congruence?

Back

Side-Angle-Side: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

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

Back

180 degrees.

Front

If two angles are complementary, what is their sum?

Back

90 degrees.

Front

What is the definition of similar triangles?

Back

Triangles that have the same shape but may have different sizes; their corresponding angles are equal and their corresponding sides are proportional.
