G. Unit 4 Part 2 Review

Mathematical Equivalence

ON

Answer explanation

Which statement must be true in this figure.

Answer explanation

There is no information proving SR and QT perpendicular.

With the picture alone we cannot prove <R and <T congruent. <R and <S are only congruent if the triangles are similar, which we cannot prove with the picture alone.

<T and <S have the same intercepted arc which means the angles must be congruent.

Answer explanation

Solve for identified arc or angle measure. Enter only the numerical values.

Mathematical Equivalence

ON

Answer explanation

Answer explanation

Since <JLK is a right angle, that means the endpoints of the angle must be on the diameter of the circle.

A square can ALWAYS be inscribed in a circle: ​ (a)  

A parallelogram can ALWAYS be inscribed in a circle: ​ (b)  

A kite can ALWAYS be inscribed in a circle: ​ (c)  

• True
• False

Answer explanation

Opposite angles must be supplementary. Neither Parallelograms or Kites hold this requirement.

Squares do follow this requirement as all angles must be equal which means every angle is 90, therefore making opposite angles both supplementary and equal
