Is the conjecture that ZAX and WAY are vertical angles true or false, and why?

True, because vertical angles are formed by two intersecting lines.

Given m 1 = 20 and m 2 = 70, are angles 1 and 2 complementary, and why?

False, because complementary angles must sum to $90^ ext{o}$, and $20 + 70 = 90$ is not true.

If M is the midpoint of AB, what can we conclude about AM and MB?

AM = MB, because the midpoint divides a segment into two equal parts.

What is the contrapositive of 'If two angles are not adjacent, then they are not a linear pair'?

If two angles are a linear pair, then they are adjacent. Signup and view all the answers

Given the equation $3x + 8 = 59 + 2x + 1$, how can you prove that $x = -8$?

By rearranging terms, $3x - 2x = 59 + 2 - 8$, simplifying to $x = -8$. Signup and view all the answers

Given that lines AB and CD are parallel, what is needed to prove that segments AC and BD are equal?

You need to show that corresponding angles are equal due to the parallelism. Signup and view all the answers

If angle 1 is supplementary to angle 2 and angle 3 is also supplementary to angle 2, how do you prove angles 1 and 3 are equal?

Both angles 1 and 3 sum to 180° with angle 2, thus $1 + 2 = 180$ and $3 + 2 = 180$ implies $1 = 3$. Signup and view all the answers

Given that segment EC bisects angle AED, and ED bisects angle CEB, how can you prove that angle 1 is equal to angle 2?

Use the definition of angle bisectors, which states that each angle is divided equally. Signup and view all the answers

How can you prove that segments AM and ND are equal if M and N are midpoints of segments AB and CD respectively?

By the definition of midpoints, both segments AM and ND each represent half of AB and CD. Signup and view all the answers

If AB is parallel to CD and BD is equal to DE, what does it imply about AD and CE?

It implies that AD is equal to CE by the properties of corresponding segments in parallel lines. Signup and view all the answers

What reasoning would you use to show that if EC bisects AED and ED bisects CEB, then angles 1 and 2 are equal?

Both bisectors imply that angles 1 and 2 are each half of their respective angles AED and CEB. Signup and view all the answers

In the triangle formed by points A, B, C, D, if M and N are midpoints and BD bisects CE, how do you validate that AM = ND?
