Please help me with a few problems

[Deepblue]

I'm currently studying up for a major test and I am struggling with some of the problems on my take-home practice test. Math is my weakness. If anyone could help me in the slightest I would greatly appreciate it.

~ Find the the length of the segment with endpoints M(-1,1), and N (3, -2)
A. 5
B. 9
C. 16
D. 25

~ If two angles form a linear pair, then they are
A. Verticle Angles
B. Supplementary Angles
C. Complementary
D. Congruent Sides

~ The measure of the vertex angle of an isosocles triangle is 108. Find the measure of a base angle.
A. 108
B. 72
C. 36
D. 18

The Relationship "is perpendicular to" has which of the following properties?
A. Reflexive
B. Symmetric
C. Transitive
D. All of these

Those four are giving me a little trouble.

~ Find the the length of the segment with endpoints M(-1,1), and N (3, -2)
A. 5
B. 9
C. 16
D. 25

look up the distance formula

~ If two angles form a linear pair, then they are
A. Verticle Angles
B. Supplementary Angles
C. Complementary
D. Congruent Sides

look up the definition of a linear pair of angles

~ The measure of the vertex angle of an isosocles triangle is 108. Find the measure of a base angle.
A. 108
B. 72
C. 36
D. 18

vertex angle + two base angles = ?

The Relationship "is perpendicular to" has which of the following properties?
A. Reflexive
B. Symmetric
C. Transitive
D. All of these

look up these three properties and provide a definition for each one
