What is the reason for statement 5 of the two-column proof? given: ∠jnl and ∠mnk are vertical angles. m∠mnk=90° prove: ∠jnl is a right angle. statements reasons 1. ∠jnl and ∠mnk are vertical angles. given 2. ∠jnl≅∠mnk vertical angles theorem 3. m∠jnl=m∠mnk angle congruence postulate 4. m∠mnk=90° given 5. m∠jnl=90° ? 6. ∠jnl is a right angle. definition of right angle -angle congruence postulate -angle addition postulate -linear pair postulate -substitution property of equality

Given: ∠JNL and ∠MNK are vertical angles and  m∠MNK=90°

Prove: ∠JNL is a right angle.

   Statements                                                     Reasons

1.  ∠JNL and ∠MNK are vertical angles.             Given

2.        Vertical angle theorem

3.        Angle congruence postulate

4.                  Given

5.                 Substitution Property of Equality

Since, the measures of angle JNL and MNK are equal and the measure of angle MNK is 90 degrees. therefore, by substitution property of equality, both the angles JNL and MNK will have an equal measure.

Therefore,  

6. ∠JNL is a right angle.                                     Definition of right angle

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
