Geometry Final Semester 1 Review

What is the definition of complementary angles?

• Two angles whose sum is 90 degrees.

• Two angles that are equal in measure.

• Two angles that add up to 180 degrees.

• Two angles that are adjacent to each other.

Which triangle congruence theorem can be used to prove the triangles are congruent?

• SAS (Side-Angle-Side) theorem states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

• ASA (Angle-Side-Angle) theorem states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

• SSS (Side-Side-Side) theorem states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

• AAS (Angle-Angle-Side) theorem states that if two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.

∠1 and ∠3 can best be described as -

• Complementary angles

• Adjacent angles

• Vertical angles

• Supplementary angles

What is the Pythagorean theorem?

• In a right triangle, a² + b² = c², where c is the hypotenuse.

• In any triangle, the sum of the angles equals 180 degrees.

• The area of a circle is πr², where r is the radius.

• The relationship between the sides of a triangle is given by a² + b² = c, where c is the longest side.

What is the definition of vertical angles?

• Angles that are adjacent to each other when two lines intersect.

• Angles that are opposite each other when two lines intersect, and they are always equal.

• Angles that are supplementary to each other when two lines intersect.

• Angles that are complementary to each other when two lines intersect.

What is the definition of supplementary angles?

• Two angles whose sum is 90 degrees.

• Two angles whose sum is 180 degrees.

• Two angles that are adjacent to each other.

• Two angles that are equal in measure.

y = 3x + 2 and y = 3x - 3. These lines are...

• Intersecting lines with different slopes.

• Perpendicular lines with the same slope.

• Parallel lines have the same slope but different y-intercepts.

• Coincident lines that overlap completely.

What is the definition of adjacent angles?

• Adjacent angles are two angles that share a common side and a common vertex.

• Adjacent angles are two angles that are opposite each other.

• Adjacent angles are two angles that add up to 90 degrees.

• Adjacent angles are two angles that are equal in measure.

What is the definition of a right triangle?

• A triangle that has one angle measuring 90 degrees.

• A triangle with all sides of equal length.

• A triangle that has two angles measuring 45 degrees.

• A triangle that has no equal sides.

What is the Symmetric property?

• The Symmetric property states that if a = b, then b = a.

• The Symmetric property states that if a + b = c, then b + a = c.

• The Symmetric property states that if a > b, then b < a.

• The Symmetric property states that if a - b = c, then a + c = b.
