IM2 Geometry and Similarity

The word “Geometry” means

• Earth measure

• Rock science

• Shape study

• Solid knowledge

How many points exist between the endpoints of a segment?

• Infinitely many

• It depends on the length of the segment

• Calculate with distance formula

An infinite path extending in opposite directions is (a)

• Point

• Line

• Plane

• Space

The reason that AA~ is a postulate and SSS~ is a theorem is

• AA~ describes a fundamental relationship accepted as true without proof, but SSS~ is a conjecture that has been proven

• SSS~ describes a fundamental relationship needing no proof, but AA~ is a conjecture that has been proven

Vertical angles are adjacent.

• True

• False

When two lines lie in the same plane and don’t intersect, we call them

• Skew lines

• Parallel lines

All of the following angle pairs could be supplementary except

• An acute angle and an obtuse angle

• A linear pair

• Two right angles

• The same-side interior angles formed by a transversal and two parallel lines

• Two obtuse angles

Which statement about congruence is not necessarily true?

• Congruent segments have the same length

• Congruent angles have the same measure in degrees

• Congruent triangles have all corresponding sides ≅, & all corresponding ∠s ≅.

• Congruent shapes aren’t always the same size

• We often use the symbol “≅” to say “is congruent to”

Adjacent angles are ∠s that

• add up to 180°

• add up to 90°

• are formed by two intersecting lines

• form a “Z” where a transversal crosses two parallel lines

• share a vertex and a side, but don’t overlap

If two angles are adjacent angles, then they are supplementary angles.

• Sometimes true

• Always true

• Never true
